capacitor 1.0.0

Instead of making ActiveRecord calls to change a counter field, write them to capacitor. They'll get summarized in a redis hash, with a separate process batch-retrieving and writing to ActiveRecord. Being single-threaded, the writing process avoids row lock collisions, and absorbs traffic spikes by coalescing changes to the same row into one DB write.
