Specifying characters in queries may fail if specified directly

This is copied from issue #99, originally reported by @slavap

q.setFilter("ch == 'a' || ch == 'z'");

Error is: Exception in thread "main" javax.jdo.JDOUserException: Query parsing error at 'a' near position 7: Incompatible types,
found 'String', expected: char. Query= ch == 'a' || ch == 'z'

The query engine is currently undergoing a major refactoring. Th bug will be fixed once the refactoring is done.

I don't think it really counts as bounty-worth, especially as it is labelled as TODO in the code :-), QueryParserV3.java, line 498. But thanks for reporting it.
