Core:

- Redesigned stealth and invisibility handling
  - Implemented the handling of multiple stealth types
- Implemented fake inebriation
- The message deliverer no longer sends packets from a non-visible source
  - The server won't send that much garbage which just takes bandwith
  - It won't be possible to use cheats to detect invisible objects
- Removed a lot of checks for the Z-coord
  - Fixes visibility problems happening while flying
- Limited the grid activation range of creatures to use less resources
- Implemented Shroud of Death
- Implemented increased visibility range for active objects
- Removed visibility check at spellhit (only sanctuary effects should prevent it)
(And a lot of other changes...)
