Made a couple changes that affect enough guilds that I didn't want to
post individually on each guild board.

1. Runes can no longer be sketched in a room that is full of water.
Pre-existing runes will not be wiped away by the introduction of water
to the room (ala elementalism flood).

2. Reverberation vibe was fixed and should protect properly against cube
sigils and eihwaz runes now.

Penned by my hand on the 22nd of Scarlatan, in the year 319 AF.
