Fixes for DB IO, DB general functions, JS core updates

DB IO
- Update/Select/Insert checks are sane now and not reverse
- UPDATE can now use RETURNING
- meta table check in postgresql is supressing warning for not existing
table and just returns false

JS (edit)
- update for the html element creation functions

Basic:
- SITE LANG settings added to change default lang based on vhost
- log file id is now set more lienient via globals and not with a global
constant

DB Tables/Functions:
- fix wrong general function and set uid function was missing
