tdf#148986 Support XF86Forward / XF86Back key events

Multimedia keys found on certain presentation clicker devices.
Not added to the Customize dialog, as that was not yet asked for.
As I have no access to a MAC, did not add support for that in vcl.

Inspiration for code taken from
commit ca74511985981444dbd72ade7244484c131e36a7
