- PGSQL friendly

New Install:
- file_get_contents

New/Old Install:
- remove remarks for PGSQL, some versions don't like 'em
- fixed the regex in remove_remarks
- rewrote split_sql_file

Schema:
- removed explicit inserts, replaced with implicit inserts. This is more friendly to our non auto incrementing friends. (One set of data is not fixed yet, the modules table)
- removed all those SELECT SETVAL statements, they were not needed.
