+ * Fixed itemdb_read_sqldb blowing up the server with segmentation faults.
+ * Added an option for parse_script to ignore the checks for the set of
+ brackets around the script. [FlavioJS]
* Removed 'into_abyss' effect on traps; tests show that it works ONLY
for Gemstones (tho' iRO website claims otherwise) - bugreport:171
- corrected code that was exploiting the flag as an 'expired' trap flag
