Changed profile matching logic

Browse Source 
Relaxed the profile matching logic to
use my looser displayidentifier logic
as it is more likely that connections to
a display is changed rather thant the
display paths, resolution or anything like
that. Will use this as an experiment to
see if it works or not.

Also fixed the shortcut renaming errors
by searching for the UUID, not the shortcut
name which is the pretty much the way
I should have done it in the first place!
