- Volcano/Deluge/Violent Gale are now interchangeable, in the sense that as long as one of these is out, casting any of the three will not consume gems, and will use the remaining time of the previous one. In turn, Land Protector will now always consume gems on every cast.

- Small cleanup in the Land protector code which may fix it not blocking AoE skills.
- Fixed the interpretation of "head_dir". Removed setting head_dir to match character direction in the whole code. Now it is only reset to 0 (look forward) when unit_setpos is invoked, or when a character begins walking. Thanks to FlavioJS for figuring out how the client parses the head direction.
