(#1533) - Reformat more lines to be < 80 char
(#1853) - make perf tests more accurate for skip/limit

Nolan forgot to actually make the "skip" values large,

outperforms skip/limit.
(#1844) - Only clean up the tests after suite is complete
(#1846) - Dont write checkpoint when replication is cancelled
(#1848) - housekeeping on query() docs

Adds more notes to the db.query()
documentation, especially when we
forgot to mention certain
parameters. Also adds documentation for
options.stale and options.group_level.

The only new code this will require in
order to be accurate is pouchdb/mapreduce#85.
