[antlr-interest] case in-sensitive literals

[mzukowski at yci.com]

The issue used to be that "AND" would be put in the literals table, but
everything coming through would have been normalized to lower case, so "and"
would be looked up an missing.  I sent Ter a patch for that.  From your
previous post it sounds like that normalization wasn't even happening before
testing the literals table.

I thought I had 2.7.2. I looked at the install.html and it says 2.7.2.
In my grammar I have "and" lower case, and it would only accept lower case.
Thanks.
