Fixes #9733: add JS code to name browser tabs individually. New GET variable 'tabUniqId' on record acquire is now saved in dirty record. On page reload, when the 'release' comes after 'acquire' (async behaviour), the locking is skipped (if same user session) - on reload there is no variable 'tabUniqId'. On real lock acquire, the tab ID is compared and will be denied if not matching. The 'tabUniqId' might not work in IE - doesn't matter: it's a seldom special situation.

Change definition of QFQ system tables for 'modified' and 'created'. Use DATETIME instead of TIMESTAMP

Fixes #8067. Feature: url-sip / url-sip-skip-history - Form forwarding can now be used with SIP encoded parameter.

Refactor to use form.restMethod instead of form.permNew|edit=rest. Next step will be to eliminate formMode=FORM_REST
