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.

Style fixes to IK, focus on docs

BCheckBox: Style fixes, variable renaming for consistency, docs.

Also some other style fixes, no functional changes intended.

BCheckBox: Add icon support

* Draw(): Remove the non-BControlLook code.
* GetPreferredSize(): Implement based on _ValidatePreferredSize() to
avoid code duplication.
* Draw(): Fix off-by-one error. The label was too close to the box.
* Draw(), _ValidatePreferredSize(): Add icon support.
_ValidatePreferredSize() is now actually aligned with what Draw()
expects. The preferred width is now a tight fit; there were three or
four pixels of empty space before.
Due to the fixed check box position the layout isn't that nice in
some situations (particularly with an icon larger than the text),
IMHO.

BControl subclasses: Override SetIcon()

... and implement Perform() action for potential later use.

BCheckBox: Add tri-state support

* Add possible control state B_CONTROL_PARTIALLY_ON and support it in
BCheckBox and BControlLook.
* BCheckBox: Add partialStateToOff property defining whether the
partial state should transition to off. Defaults to false (i.e.
partial to on).

Interface Kit: Adjust max size and default alignment...

...on controls where it makes sense:
- BRadioButton and BCheckBox now return their preferred size as their
maximum.
- BRadioButton, BCheckBox and BTextControl now use left alignment by
default, as this is the most common use case for them.

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

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.

* Cleaned up the header
* Reordered methods to group them logically
* Use nothrow version of new when instantiating BCheckBox from archive.

no Invalidate in BControl::SetValue, I figure more controls need to be updated for this change
