tested some of lars changes, we found out that we need to back port some plsql for 4.6.3. see bcms-compat.sql. i have also spotted a change behaviour on bcms::item::get_item_by_url
added bcms::parse_properties helper proc, revised bcms::revision calls to use this helper proc. also removed www dir to move bcms as a service package. also added some plsql patches for CR, not fully tested so plsql remains part of bcms still not yet CR
