Character configuration knobs, more styling

Added controls for leveling characters and specifying their "any" deity.
Configured devotion so that "any" devotion pours into the deity of
choice. Also tested the devotion panel; seems to work.

Did some more styling on the "character" page, including addition of a
.mini_column class in the main _style.css sheet. This makes it pretty
easy to creation sub-columnar layouts.
