EQ settings: Rework the settings to clean up the config file.

Instead of 3 cfg lines per eq band there is now a single line
for each:
<config name>: <cutoff/center freq>, <q>, <gain>

In addition, the config value names make a bit more sense.

The old settings are still readable but config.cfg and any new
settings files will be written with the new config values. (The
old settings will be removed completly sometime after the next
stable release).

Also a slight rework of the advanced EQ menu UI
