Implementation of Item Options System.

Allows the infusing of equipments with bonus item options.
This feature is constrained to clients of packet versions greater than or equal to `20150226`.
Item Options and their effects are defined server-side in `db/item_options.conf` and client side in `data/luafiles514/lua files/datainfo/addrandomoptionnametable.lub`
The ID of the option must tally with the correct index of the description provided in the client side lua file to avoid bugs.
IT_OPT_* keys and MAX_ITEM_OPTIONS macro are also exported from the source as constants.
An additional flag `disable_options` has been added to sql, and as `DisableOptions: true/false    (boolean, defaults to false !!for equipments only!!)` to item_db.conf files.
Script commands documentation is also included.
SQL file updates are included.
