Merged from MOODLE_18_STABLE
Our changes:
* adodb-lib.inc.php - forced conversion to proper numeric type in _adodb_column_sql()
+ * drivers/adodb-mssql_n.inc.php - Fixed one bug in the N' parser when one value start by '
+ Once fixed by adodb guys, we'll return to their official distro.
* drivers/adodb-odbc_mssql.inc.php - Fixed one buggy function (ServerInfo) that was not
working properly. Simplified logic (now that we are FETCH_ASSOC). Work in progress
for the annoying http://tracker.moodle.org/browse/MDL-6877.
