Put a limit on sound resolution

[jobukkit]

I accidentally set the sound resolution to 22500048 and it caused Rainmeter to lock up, and lock up again on startup. I had to manually edit variables.ini to fix it.

The settings meter slider for the sensitivity cannot push over 100. The lua scripts shouldn't force a max value by hard coding 100 as max value, in case someone wants to push over it through the variables.inc.
