[PATCH (GITK) v3 3/6] gitk: Add accelerators to frequently used menu commands.

[Alexander Gavrilov <angavrilov@gmail.com>]

This commit documents keyboard accelerators used for menu
commands in the menu, as it is usually done, and adds some
more, e.g. F4 to invoke Edit View.

The changes include a workaround for handling Shift-F4 on
systems where XKB binds special XF86_Switch_VT_* symbols
to Ctrl-Alt-F* combinations. Tk often receives these codes
when Shift-F* is pressed, so it is necessary to bind the
relevant actions to them as well.
