trigger availability of some activities based on rules

[jtauber]

Currently, the only thing triggering availability of an activity is the adoption-level / number-of-people-who've-already-done-it combo.

It would be nice if there were other rules for when an activity is available. Perhaps an activity is only available once another has been completed. Or done N times. Or based on the result of a survey question. Or when a particular ability with a concept is established.

The core should probably support all of these.
