HQLPARSER-17 - More operators for Lucene

@Sanne, some remarks:
* For _<_ and _>_ queries to work 100% correctly [HSEARCH-1378](https://hibernate.atlassian.net/browse/HSEARCH-1378) is required, as the DSL mixes up the exclusive flags for range queries; I've @Ignore'd the concerned tests for the time being
* _LIKE_ queries are limited to single words (with wild cards) atm.; I'm not sure how this could be made working with phrase queries, but according to to @anistor's comment on [HQLPARSER-17](https://hibernate.atlassian.net/browse/HQLPARSER-17) this seems to be not really required as of now; What's your take on this?
