old experimental hacky code, no longer used
some optional useful debug msgs
Fixes #15:
- merged the computing of slot ID's (order-values and facets now use the same mechanism)
- this means that slot ID's are no longer continuous for a single facet (doesn't matter anyway that they are)
- prefixed order-value with... 'ordervalue' e.g. 'eprint.ordervalue.title.en' for ordering the eprint dataset by title in english
- removed no longer needed constant in Xapian.pm
- partially reverted https://github.com/eprints/xapianv2/commit/e159e90acc7142560f44ff9d41dcaa12eba28c5b cos it breaks default EPrints search pages (sorry Jiadi)
- removes any un-unsed phrases (were used by my proof-of-concept)
Merge branch 'master' of github.com:eprints/xapianv2
