The TaggerRequestHandler now supports a new boolean Request Parameter 'allowSkippedTokens' that can be used to allow skipping of tokens. By default UnsupportedTokenExceptions are thrown if the query time Analyzer emits tokens with 'posInc == 0'.

This also adds three unit tests for testing (1) the default (2) deactivating and (3) activating the feature.

@David: Hope you can come up with a better name for the new request parameter.
