Some proc-related fixes

[kjartan]

After the next crash or reboot, there will be some fixes to long-standing problems with the procs.

1. the double-proccing should be gone (which includes double-bashing, etc.)

2. the stun skill has been completely rewritten. It now actually does what it is supposed to do: suppresses procs.

3. the bard songs 'sanctuary for the body' and 'sanctuary for the soul' will actually work now. (They also suppress procs)

4. some of the caster mobs will be a little bit smarter. This may not be a noticeable effect.

Now that these skills and songs actually work, we may find that they are too powerful and have to turn them down. My feeling is that if you are fighting a mob that used to be challenging to you, you shouldn't be able to totally or even mostly suppress its procs by either stunning or singing at it.

Does it mean that suppressed proc will provide less mana drained with the help of spectral shield?
