Add syntax highlighting / textmate scope for numbers (again)

[ShadowCreator250]

Apparently, this extension doesn't recognize numbers (anymore). I know from #27 that it once had this feature. Numbers are now only recognized as simple properties (Command Palette > Developer: Inspect Editor Tokens and Scopes):

Is it possible to match only numbers with 1 . in them? This would prevent #27.

A suitable (partial) regex could look something like this: ([+-]?)([0-9]([0-9_]*[0-9])?)(\.[0-9]([0-9_]*[0-9])?)?$
