Auto-freeze, fixed <select>, added option for collapsible columns to themes, ...

... fixed 'Any Knife' getting market priced.

Auto-freeze (fix for #86) hasn't been tested when failing (for once, CSGOLounge refused to fail), but has been tested to not break other requests.
Because you set it to be enabled by default, and very few people want that, I'm assuming that all those who left it at default (i.e. "1") want it disabled. Those who want it enabled will think "huh, why did it start showing again?" and check settings. If I did it the other way around, those who left it at default due to not checking settings wouldn't check settings now either.

Since I can't use "1" for enabled any more, I use 2. That means there's no option with a value of 1, so leaving the option at 1 would fuck stuff up.
