Subject: [PATCH] Remove apparently unused ignoredTokens field from parser.txt
template
This field seems to store all ignored tokens encountered during parsing.
It's not clear what this field is meant to do - we don't use it for
anything, and neither does SableCC itself apparently. Removing it
doesn't seem to break anything and should improve memory usage during
parsing a bit.
