Queries with partion keys will be accepted. This fixes issue #37 and issue #50
#37: Fix handling of escaped quotes in CqlWhereParser. The parser preserves types of literals - e.g. it is now possible to distinguish string literals from number literals in the generated AST. Throw error when filtering on incomplete partition key. Code cleanup, fixed a few warnings.
