Terminal: load themes from data and settings folders.

* Uses the same format as the Terminal settings file
* Adds an additional key, "Theme name", to settings for themes,
which needs to be present for a theme to be loaded, else it
will be skipped
* Loads themes from Terminal/Themes in the data and settings
directories, searching data first, then settings second,
allowing a theme to be tweaked by putting a copy in a
settings folder

Solarized Dark and Light color scheme for Terminal

Signed-off-by: Alexander von Gluck IV <kallisti5@unixzen.com>

include strings.h where appriopriate...

instead or additionally to string.h, in preparation for functions move.
* moves str[n]casecmp() functions and others to strings.h.
* strings.h doesn't include string.h anymore.
* this solves #10949

CodeStyle fixes, some refactoring and cleanup

* Clear some codestyle issues catched by checker script;
* Rename RestartDebugCapture to more consistent StartStopDebugCapture;
* Updated Copyrights and authors lists, some occurences of the raw MIT
licence text replaced with "under the terms of MIT licence" reference;
* Fixes for x86_64 build.

This is cumulative cleanup commit for series of Terminal refactoring
changes I have introduced last time. No significant functional changes.

OSC and color management improoved

* Global kTermColorTable replaced with it's private copy for every
TermView instance. This allows to modify colors table for every view
separately;
* Set of ANSI normal/bright color entries added into preferences;
* Default color table generated dynamicaly using ANSI colors
preferences. 6x6x6 color cubes and grayscale ramp are generated in
xterm colors model;
* Improoved support of Operating System Command control sequences;
* Support for X11 rgb.txt compatible color names. Corresponding entries
are stored in hashed form in application resource and loaded only on
demand.

Revert "Make Default color scheme match default settings..."

This reverts commit 72bf9c4e480784cde000b41982f3afb6f7d00e2a.

I fixed this the wrong way.

Change the cursor from white to yellow for blue theme

matching the text color. The white was a little off.

More style fixes, return true or false directly

Make Default color scheme match default settings...

So that it gets selected, well, by default. Before Custom was
being selected initially.

Style fixes only, no functional changes intended

including converting a while loop into a for loop.

Change schema in Terminal to color scheme.

Love this feature, but, color schema is not a thing, it is a color
scheme. Change both the display text and the variable names.

Also changed "Retro Terminal" color scheme to just "Retro". Terminal
is redundant.

Terminal: Spice up terminal color scheme selection

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.

Applied patch by Disreali, adding colour scheme green on black. Fixes #7977. Thanks.

Style.
Add NULL guard to the color schemes struct, although the code was safe
neverthless (for now)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37575 a95241bf-73f2-0310-859d-f6bbb57e9c96

Obviously, just checking for the text color isn't enough.
Also renamed colors to schema since it makes more sense


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37536 a95241bf-73f2-0310-859d-f6bbb57e9c96

Add a menufield to select color combinations, and add obvious
"white on black" and "black on white". For some reason these aren't
applied live, like when you chose a custom combo.
I'm not really fond of the code, and will rework it in the next few days.
But at least it works!
