ipmanager & InterfaceMgr: 2 new elements
* prepare adding custom options to database
* added new function ajaxEchoNC for callbackForms with errors
InterfaceMgr: better animation when using setPopupContent. Also use ajaxEchoNC on some useful locations
Interface management: added new class to manage table (basic for now)
HTMLTableMgr: rendering is now ready. we must implement it on every component
HTMLTableMgr: add rendering for add/edit (also experimental, we must implement it everywhere)
hmm it's not ready for some custom fields
