Character Map: Added larger character popup on left-click

Fixes #15983.

Added left-click support to the existing function that pops up the context
menu for copying characters. Instead of menu options, put a large version
of the currently-selected character in the popup on left-click. The popup
character is 2.5 times as large as the current font size, because that
seemed nicer than 2 times.

Right-click functionality is unchanged.

CharacterMap: gray out blocks that aren't supported by the current font

Fixes #15982.

Added font to UnicodeBlockView. Cache Unicode "Blocks" for both
UnicodeBlockView and CharacterView. Added lookup of non-Be Unicode blocks
(i.e. blocks with 'kNoBlock' specified). Gray out non-found blocks.

NOTE: tested fontconfig extensively in another environment and the shown
blocks match what fontconfig returns. However, you may sometimes see
characters in blocks that aren't 'included' in a font. I haven't figured
out why that occurs.

CharacterMap: The CharacterView is scroll-view aware.

Fixes #14897.

CharacterMap: Use binary searches rather than linear lookups where possible.

UnicodeBlockView::SelectBlockForCharacter and CharacterView::_FrameFor
use the same linear search to find which block a character is in, so I
refactored both to use a shared BlockForCharacter function in UnicodeBlocks.cpp
that is a binary search. CharacterView::_BlockAt also had a TODO comment to
use a binary search, so I rewrote it as a binary search. It's not the same
search as the aforementioned BlockForCharacter function. These two changes
ought to improve the overall performance of CharacterMap.

CharacterMap: avoid white outline around selected character

SetLowColor() to the highlighting colour before drawing a selected character
to avoid blending with the regular white background.

apps: Convert to using Set*UIColor.

CharacterMap: several fixes to char. view scroll

* Select items in the encoding list by block identifier rather than
list index (there are holes in the list)
* Scroll to the start of the list when the application starts
* Add and use IsBlockVisible to detect when we need to make a block
visible, avoiding unwanted scrollings in some cases with the previous
method of testing for only one character in the block.

CharacterMap: select Unicode block for current character

Fixes #3651, part 1

More catalog-related cleanup.

* rename B_TRANSLATE_CONTEXT to B_TRANSLATION_CONTEXT and
B_TRANSLATE_WITH_CONTEXT to B_TRANSLATE_CONTEXT, squashing a TODO
* adjust all uses of both macros in Haiku's source tree
* use correct header guard for collecting/Catalog.h

The renamed macros require adjustments to all external applications
using catalogs.

Patch from Jason Fagnière (Protonux) as part of GCI :
* i18nize devices, charactermap, cdplayer, activitymonitor.

Thanks!

* Added CharacterView::ScrollToCharacter(), and IsCharacterVisible().
* On text drops, the character map is now scrolling to the first character
dropped. This is helpful to see the code of a character as well as the block
it is contained in.
* Fixed a bug in CharacterView::_FrameFor() that would not return the correct
vertical position.
* Made a few methods const.

Patch by Humdinger:
Updated Haiku apps to use sentence-case. What a huge undertaking...
The files where I had to apply the patch manually (for mysterious
reasons) have also gotten a whitespace cleanup. I've proof-read
everything so hopefully there should be no problems.

This should be the final part of #5169.

* _GetCharacterAt() might actually fail - this fixes a bug causing the bitmap
initialization to fail. This also caused a crash, as that wasn't checked for
before.

* Reverted r30529 as this was pretty much bogus (sorry stpere, but the size of
the window was already set with its constructor).
* Fixed the actual cause of bug #3752 instead: the fCharacterHeight and
fTitleHeight members were not initialized when MinSize() was called.

while you were already over another character.
