Performance improvement: disable OptimizeOnCommit by default
Updated solr binaries to 4.6.1
Removed accidentally comitted runtime files, adapted .gitignore accordingly
New build of custom ezfind solr requesthandler, adapted version number in build file

Properly ignore run time directory if present
Re-added master slave config as a run time option
Moved default core files into a proper directory
Updated .gitignore with data subdirs in any level
Changed default core name to ezp-default as configured in out of the box backend
Using XInclude: separate out language specific field types and analysis for easier upgradeability and additional languages
