NEW: module_system | changelog -> added a helper method in order to get the changed properties of an object
NEW: module_search | indexer -> indexObject got a new param "bitForce", used to force the indexing of an object (e.g. when updating the complete index)
NEW: module_search | indexer -> started implementing a conditional object indexer, only usable in combination with the change-history. validates if an object changed and triggers the search-index update only on changed objects
BUG: module_system | changelog -> refactored some parts of the changelog handler. the internal cache of old values is no longer updated automatically.
NEW: module_search | indexer: the indexer validates against the changelogs' init cache, no longer the last updated / latest version
NEW: module_search | indexer: added a debug performance evaluation for changelog based indexing
NEW: module_search | indexwriter -> removed some duplicate code
NEW: module_search | indexer: the contents of a single document are added with a single insert, no longer separate ones
NEW: module_system | changelog -> mutiple changesets are inserted with a single query rather than using multiple queries in a loop
NEW: module_search | indexer: the perfomance debug test prints the number of sql queries, too
Merge branch 'features/fastindex'
