GUI: Added in-place hotkeys for widgets.

Now it is possible to specify hotkeys in place for ButtonWidget
and CheckboxWidget (the only widgets with hotkeys now).

Use de-facto standard with putting hotkey between tildes (~).
Like '~O~pen'. The tildes gets stripped before after hotkey
is extracted.

This is done for giving translators possibility to specify
their own hotkeys.

Old hotkeys defined at widget instance creation are left for
leaving possibility to specify non-printable hotkeys such as
Common::ASCII_ESCAPE.

Translation files were updated respectively.
