Simplify some regular expressions

Browse source 
There's a fair number of regular expressions througout the code-base which are slightly more verbose than strictly necessary, in particular:
 - We have a lot of regular expressions that use `[0-9]` explicitly, and those can be simplified to use `\d` instead.
 - We have one instance of a regular expression containing a `A-Za-z0-9_` sequence, which can be simplified to use `\w` instead.
