Added new item bonuses bFixedCast, bVariableCast & bFixedCastrate (see 'doc/item_bonus.txt' for info).
Added new conf for max_walk_path.

* bb61951:
Getting rid of unused indexes.
If the table has a multiple-column index, any leftmost prefix of the index can be used by the optimizer to find rows. For example, if you have a three-column index on (col1, col2, col3), you have indexed search capabilities on (col1), (col1, col2), and (col1, col2, col3).

* 7e4c578, 90eefa0:
Allow unsigned int values for guild exp (as it was before the change).
Atoll was introduced in a 2011 lib and vc9 and 10 don't have that, dropping to atol since we dont need the int64 and using a tricky conversion to get it to unsigned.
