6 hours to fix my antlr netbeans plugin

Used near 6 hours to fix my netbeans-antlr plugin. I have to remember these:

1. Netbeans build in antlr library have to in-sync with the antlr i am using in my pluging. If they in different version, unexpected result will come out.
2. In windows, if antlr grammar has some mistakes (I meant not problems, your grammar still works). Then the netbeans-antlr panel unable to retrive all rule names. I added a test case for this.
