Finally I had time to code the update.

Added:
- Thirstforwater.tfw.vip - With this permission, thirst is spent longer (x2 slower).
- seems like I fixed the ability to turn off running when there is little thirst.
- /tfw enable | disable - command for enable/disable plugin (
Thirstforwater.tfw.settings).

In update 1.9 I will add a jar with filters.
