name-parser: Set UniqueID

Browse source 
[why]
When we rename a font we should always also change the unique ID.

[how]
Take the fullname and the Nerd Font version number. In general we do not
have the version number in the NameParser object; but we have the
'Version' name and we loot the last word (which we have set to the Nerd
Font version already in the patcher) as version descriptor.
