* Database updates:
- Updated Renewal item_combo_db with new item entries.
- Updated Renewal item_noequip with Vellum gears/siege items.
- Some small updates to Renewal item_db.

* Other changes:
- Added some towns to various Renewal mapflag files.
- Fixed two typos in Nameless Island quest. (bugreport:8021)
- Fixed an error with the '+=' operator on string variables. When attempting to concatenate and assign to a previously empty string with +=, it'd throw a memory manager error. (Hercules 1afeabf)

Safecheck atcommand

-Add restriction for atcommand to prevent possible mapcrash from script
or console usage while waiting full portability.
-Upd athena-start for new default binname.
-Remove petstat as it was similar to getpetinfo and copy only missing
attribute level atribute into getpetinfo.
-Merge useatcmd and atcommand as they shared quite the same code, also
properly differenciate useatcmd from normal player call.
--Upd script-documentation about it thx Euphy.
