Allow node ids with keywords as suffixes

Browse Source 
I've extracted alpha and punctuation characters from the huge regex and
made multiple occurences of alpha characters be recognised as a single
ALPHA token.

This way everything should work just like before, with the
difference that alpha strings will swallow keywords, ie. `spend` is
`ALPHA`, while previously it would have been `ALPHA ALPHA end`.
