Support %e (cur.encoding) for Terminal titles

Optional parameter %e to indicate current tab view encoding in the
window title. It is not shown in case tab view encoding is default
UTF-8. Inspired by Sergei Reznikov. Thanks.

Omit Terminal Id title in case single app instance running

Hide the current index of Terminal window from it's title if only
ony instance of the Terminal application is running in the system.

Fixes #9530.

%T placeholder (localized Terminal name) for title mask

* %T placeholder added into the set, available for customizing main
Terminal window title. It should be typically replaced by the
application name localized for the currect system locale.
* Use B_TRANSLATE instead of B_TRANSLATE_SYSTEM_NAME for the first
menu entry in the main TermWindow menu. The meaning of "Terminal"
term in this menu is the "Terminal session" but not the "Terminal
Application" so using separate catkeys entry for this menu item
avoids this inconsistency in Terminal UI localization;
* Fixes #7586

* Removed the shell process ID from ActiveProcessInfo and moved it to new class
ShellInfo, which also contains a flag whether the shell is the default shell.
* If the Terminal has been started with a custom shell, also replace "%p" in
the title by its name, when active.
* Also show the on-close alert for the custom shell.

Fixes #6844.

Removed debug leftover.

As suggested by Humdinger, replace "%p" by "--", if the shell is the active
process.

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.
