Fixed sql char deletion code using a broken pet deletion query (ran very slow, and had a typo in a binary shift operation) (bugreport:3304).

Fixed change r13774 to the code responsible for deciding whether to move 1 extra cell when stopping walking; it had its logic inverted by mistake (bugreport:3312).
Cleaned up the itemlist, cartlist and storagelist gm command code:
- fixed buffer overflows in all three functions (bugreport:456).
- merged all three atcommand functions into a single one; the appropriate behavior is detected from the command's name.
- using the StringBuf class instead of static-size buffers and string operations for more efficient and safe processing.
- using 'jname' (the one without underscores) as the primary item name in the list, and not using the aegis name for cards at all (since it's almost identical).
- fixed forged item details never being displayed due to a missing strcat().
- extended item info (crafted/named items, pet eggs) will now be displayed for storage and cart list as well.
