Produce one filter box above the event list per (view) menu block in the left column

If I select filters from two different groups, the x-outs are mingled above the events. Better to have a line of x-outs per group, a la San Diego.

That's the plan. What you currently see is stage one: output an arbitrary number of menu blocks. Stage two: have them each generate a separate filter box that (by default) work in concert like so:

(FILTERBOX1: this or that) and (FILTERBOX2: this or that)

if a query is also included, we add

(QUERYFILTER) and (FILTERBOX1: this or that) and (FILTERBOX2: this or that)

Later versions may allow an advanced mode in which arbitrary boolean expressions may be built by the user.
