admin/sqlpatch.php bug

[emupilot]

using zc 1.3.7 i noticed when looking through the db after running a 'create table' query (that failed) with sqlpatch.php that the upgrade exceptions table was empty. however, there was another table with two DB_PREFIXes that contained the errors (e.g if your db prefix was x_ the errors would be in a new table named x_x_upgrade_exceptions).

the problem was that the constant TABLE_UPGRADE_EXCEPTIONS already contains the constant DB_PREFIX but the functions in sqlpatch.php add the prefix again (including the function that test for the existence of the table).

i have attached a fixed sqlpatch.php that corrects the problem by removing the unnecessary additional DB_PREFIXes and corrects the broken call to zen_table_exists() on line 644 without changing the function so as not to break other calls to it.

i tested this with my own install and all further errors appeared in the correct table.
