Appearance: Remove "sub-pixel anti-aliasing is not enabled" message.

FreeType 2.8+ uses a non-patent-encumbered algorithm for this by default,
and as we have used it for quite a while now, this message is obsolete.

preferences: Convert to using Set*UIColor.

Patches 0023-0037 from looncraz, unmodified.

* Added a third hinting mode: monospaced fonts only. This is especially helpful
with low resolution devices like the EeePC - small fonts can look pretty bad
when hinting is turned on, and you still have the advantage of hinting for
text editors and the terminal.
* Added a ServerFont::Hinting() method (that currently only evaluates the
global hinting setting).
* Added a TODO comment on why having global settings is not what we aim for.

Use layout management for all of the window. Can be improved by making
the listview use all the available additional size. But works far better
than before.

* Use layout management in the AntialiasingSettingsView.
* Remove unused code.
* Remove INSTANT_UPDATE define, I guess instant update is always wanted.
* Replaced text control for setting the "averaging strength" with a slider
and hopefully improved label.
* Simplified other labels a bit as well.
* Added detection of subpixel rendering availability by peeking into the
Freetype option header. If it's not turned on, then the controls are not
displayed and instead there is a text explaining the problem and hinting
at what needs to be done in order to enable the feature.

Patch by Andrej Spielmann (GSoC):
* Simplified the subpixel related methods for the AGG "pixel format" template
interface, the ones for the solid cover simply pass through the existing
methods, so only one subpixel blending function is left which does the actual
work (this removes a lot of the previously added code)
* Implemented a new rasterizer based on the original AGG rasterizer which
implements subpixel anti-aliasing for any generic AGG vector pipelines. It
is now optionally used in Painter and AGGTextRenderer (for vector fonts, ie
rotated, sheared or big enough fonts) depending on the global subpixel
setting.
* Put all subpixel variables into the new GlobalSubpixelSettings.h|cpp
* Simplified DesktopSettings related classes a bit and renamed previous
FontSubpixelAntialiasing to just SubpixelAntialiasing.
* The private libbe functions for subpixel related settings moved from Font.cpp
to InterfaceDefs.cpp where other such functions live. They are not related
to fonts only anymore.
* Removed the subpixel related settings again from the Fonts preflet and added
them to the Appearance preflet instead.

All of the above implements subpixel anti-aliasing on a global scale, which
to my knowledge no other OS is doing at the moment. Any vector rendering
can optionally use subpixel anti-aliasing in Haiku now. The bitmap cached fonts
are still affected by the Freetype complile time #define to enable the patented
subpixel rasterization (three times wide glyphs). Vector fonts and shapes are
not affected though at the moment.
