Removed dead code
Removed some redundant options from HQL parser.

Rule option "greedy=true" is not needed (it is set to true by default, see https://theantlrguy.atlassian.net/wiki/display/ANTLR3/Rule+and+subrule+options)

Maybe it's a leftover from Hibernate's ANTLv2 grammar?

NB: diff has weird whitespace in order to minimize changes in generated code.
