Enhanced special support

- Made the current charge being saved.
- Added script binds:
  - chr_set_special_recharge_speed
  - chr_get_special_recharge_speed
  - chr_set_special_mana
  - chr_get_special_mana
  - get_special_info
- Added special info lua class. Functions:
  - name
  - needed_mana
  - rechargeable
  - on_use
  - on_recharged
  - category

Further the engine no longer sets charge to 0 after using of specials
this allows more flexbilillity (like failing specials).

Changes on the xml database:
- recharge renamed to rechargeable (needed by client and server)
- needed - the needed mana to trigger a special (server only)
- rechargespeed - the defailt recharge speed in mana per tick (server only)
- target - the type of target (either being or point) (server and client)

I also made the lua engine pushing nil instead of a 0 light userdata when
the pointer was 0.

Database update needed.

Change is tested.
