change SQL on the db_* calls to {}, made the api doc better. removed -content_type on bcms::revision::list_revisions. bcms::revision::set_status now throws an error
making include names consistent. Adding include contracts to the includes (needs review from Lars). Moving simulation::template procs into new file. Starting to implement the template delete feature
Replaced dotlrn::get_user_name with a call to acs_user::get, because that proc is also cached, but the cache there is flushed correctly when the user changes his/her name
