Changes:
1. added single aliases bounded to the keys, in order to maintain easier
the binds;
2. cleaned up binds;
3. updated Keyboard menu and fixed searching binds.
Remark: aliases bounded to the keys shouldn't have leading and trailing
white spaces, if they are present in Keyboard menu, otherwise they won't
be found. So construction like, for example: bind SLASH [ key_commandline ]
is inadmissible.
4. Alternate edit binds (default disabled) moved to
config/opt/alternateeditbinds.cfg and removed old_editbinds variable.

curmenu gives back the name of the currently open menu, which can be used
to close just that.
The new script "closecurmenu" uses curmenu to close the current menu.
