BStringView: add support for multiline strings

* Actually draw the string at the bottom of the frame.
* Unfortunately BStringList cannot be cached because there is no
space left in the class.
* Change SGI and PNG translators to use it in place of BTextView.

Set*UIColor, etc.

The inseparable changes necessary to support live color updating across the
system in a sane, safe, and performant manner.

BView gains:

HasSystemColors()
HasDefaultColors()
AdoptSystemColors()
AdoptParentColors()
AdoptViewColor(BView*)
SetViewUIColor(color_which, float tint)
SetHighUIColor(...
SetLowUIColor(...
ViewUIColor(float* tint)
HighUIColor(...
LowUIColor(...
DelayedInvalidate()

BWindow gains a simple helper method:
IsOffscreenWindow()

BMessage gains:

AddColor()
FindColor()
GetColor()
HasColor() * allegedly this API is deprecated, but I implemented it anyway
ReplaceColor()
SetColor()

Previous private ColorTools methods are made public and moved into GraphicsDefs:

mix_color, blend_color, disable_color

These are fully compatible with BeOS dan0 R5.1 methods and are just code cleanup
of BeOS example code under the OpenTracker license.

In addition, four new colors are created:
B_LINK_TEXT_COLOR
B_LINK_HOVER_COLOR
B_LINK_ACTIVE_COLOR
B_LINK_VISITED_COLOR

These changes are documented in their proper user documentation files.

In addition, due to a history rewrite, B_FOLLOW_LEFT_TOP has been defined and
used in lieu of B_FOLLOW_TOP | B_FOLLOW_LEFT and is included in this commit.

On the app_server side, the following has changed:

Add DelayedMessage - a system by which messages can be sent at a scheduled time,
and can also be merged according to set rules. A single thread is used to service the
message queue and multiple recipients can be set for each message.
Desktop gains the ability to add message ports to a DelayedMessage so that
said messages can target either all applications or all windows, as needed.

Desktop maintains a BMessage which is used to queue up all pending color changes
and the delayed messaging system is used to enact these changes after a short
period of time has passed. This prevents abuse and allows the system to merge
repeated set_ui_color events into one event for client applications, improving
performance drastically.

In addition, B_COLORS_UPDATED is sent to the BApplication, which forwards the message
to each BWindow. This is done to improve performance over having the app_server
independently informing each window.

Decorator changes are live now, which required some reworking.

BStringView: added truncation support.

* Added new truncation mode B_NO_TRUNCATION.
* The Truncation()/SetTruncation() methods itself are Dano-compatible,
however, there was no B_NO_TRUNCATION.

Style fixes to BStringView related to docs

Add missing space before opening brace.

Override the LayoutAlignment method in BStringView.

Left align StringViews using layout API by default falling back
to the alignment settings set by SetAlignment() only if
SetExplicitAlignment() is not used.

This way StringViews are left-aligned by default, can be changed
using the Layout API, and the pre-Layout API legacy method is used
as a fallback.

See this thread for details:
http://www.freelists.org/post/haiku-development/Can-we-make-BStringViews-MaxSize-BSizeB-SIZE-UNLIMITED-B-SIZE-UNSET-by-default

De-virtualize BView::InvalidateLayout() and introduce LayoutInvalidated() hook, like BLayout.

Ooops, fix the binary compatibility I introduced.

Cache text width to avoid calling StringWidth() too much while
both text and font don't change.

Optimized includes. For example, BeBuild.h is almost always already included
via SupportDefs.h.

Finished unifying the Interface Kit headers:
* Fixed copyrights (puncuation and capitalization, removed authors from
headers)
* Updated indentation style
* Unified pointer/reference style
* Re-ordered some methods for better grouping where it could be done
(abd adopted source accordingly)
* Small coding style fixes here and there

No functional change intended.

* Implement SetFont() and invalidate the layout. More controls should probably
do this.
* Fix build, appearantly I made a last minute change in Draw()...

BTW, confirmed that adding virtuals declared in the base class is ok for
binary compatibility.

* Cache a fPreferredSize following the example of BButton. Changed
GetPreferredSize() accordingly.
* No longer adds margins to the left/right side and top/bottom. These will
make it difficult to make exact visual alignments with other controls and
labels.
* Invalidate the layout in SetText().

* use GetFontHeight() instead of: BFont font; GetFont(&font); font.GetHeight(...)
* fixed odd unarchiving of the alignment.
* cleanup.
