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

Terminal: Allow use of Option as Meta key

Add a configuration setting that allows the left Option key to be used as a
Meta key, and add support for the Escape sequences that control the Meta key's
behaviour.

TermWindow now maintains a copy, shared by all its component TermViews, of the
current key map, and updates this copy automatically when notified by the Input
Server a new key map has been loaded.

The Meta key was an extra modifier key present on early UNIX workstations that
provided access to the "extended" portion of the ASCII character set. Although
it has vanished from modern keyboards certain UNIX software still relies on the
key, most notably GNU Emacs and the GNU readline library, the latter of which
is used by bash and a wide variety of other software that reads input from a
terminal. (Python's interactive mode uses readline, for instance.)

With this patch applied and the new setting enabled, the left Option key can be
used to access additional editing and navigation features at the command line.
It also makes usable the port of GNU Emacs currently available from HaikuDepot.

Fixes #15294.

Terminal: always use bright for bold text.

* "Allow bold font" now enables the use of the bold font for bold text.
* so one can now see bold text in black on black.

add window size and encoding to terminal prefs

* The menu items now only set the values for the current window without
saving,
* The settings in the preference window are persistent,
* The "save as defaults" menu item is removed.

Fixes #5030.

Terminal: Add option to use bright instead of bold text

A saturated add was chosen instead of tint_color, as the results of
tint_color were too extreme.

Keep color control enabled after color scheme change

Fixes #9532

Unify the Font menu and Font size menu into one.

The Font size menu becomes a submenu of Font so that you can set
both the font and font size at once.

This fixes #4198

Add font sizes to Font Size menu in addition to in settings

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: Make cursor blinking an option.

Implemented support for dynamic tab and window titles:
* Added settings for tab and window titles. Both are strings with optional
placeholders for tab/terminal index, currently active process name and
current directory.
* Added a generic utility class PatternEvaluator that allows to expand this
kind of pattern strings and callback classes
[Tab,Window]TitlePlaceholderMapper that provide the specific expansion for
the tab and window title placeholders.
* TermWindow:
- Separated the notions of session (== tab) and window titles. The tty
clients no longer set the window, but the session title.
- Use the patterns instead of the hard-coded window/tab titles.
- Recompute all titles once a second, so changes of running programs are
reflected.
* The default patterns for tab and window titles are "%1d: %p" (last CWD
component and name of the running process) and "Terminal %i: %t" (Terminal
ID and active tab title). Unfortunately the space on the tabs is seriously
limited, so that the tab title is virtually always truncated. Ideas welcome.

Terminal will issue an alert, if there are active processes and the
user closes the window (doesn't work if the user closes only a tab, yet).
Active by default but can be disabled by a checkbox.
- The preference window needs to be reworked.
- Wording of the alert and the option can be improved (I accept advices).

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!
