Fixing filters.

Browse source 
I didn't realize they were so broken.
The fix is safe and should not break plugins or anything else.

Rambetter on Sun Jan 23, 2011:
What follows is a discussion of the introduction to some new members and functions
such as baseFilters, baseFilterExcludes, FilterAddImpl(), and so on.
There was a problem that "base" filters were not taking effect as a result of
user action such as clicking a filter checkbox. The reason why the base filters
were not being updated is because the previous logic of updating the filters had
been commented out. It was commented out because the previous logic deleted ALL
filters (including plugin filters) and re-created only the base filters. So in
effect, all plugin filters would be deleted whenever a filter checkbox was altered.
So, we need some way of knowing which are the base filters so that we can take
action when a filter checkbox is marked [or unmarked]. Then we can update
the base filters by either deleting and recreating them, or by changing their
active state in an intelligent manner. I am choosing to do the latter.
My goal here is to preserve the structure bfilter_t completely as it has been
historically. I feel that modifying bfilter_t is dangerous with respect to breaking
plugins. So what I'm doing instead is tracking which are the base filters via
external array, baseFilters. The array baseFilterExcludes keeps track of the "exclude"
parameter for the corresponding filter.
