Fix auto-capitalisation disabling locked shift

Browse Source 
Shift locked via the "caps lock" key use the "fake pointer" mechanism
that is also used by auto-capitalisation.

Make sure that unlatching a fake pointer do not disabled a locked
modifier.

The implementation is moved into the Pointers class for a safer API and
easier implementation.
