This fixes a small memory leak in our queue workers, where we don't
reset the accumulated times contained in our query logging data.
Longer-term, we may want to make something mergable for mainline where
we only store on the connection object the totals; that would be a
fixed amount of emmory per connection and thus not have this problem.

Safari doesn't let you (shift-)tab to buttons, so we have to support
this ourselves in several cases.

Now we can nest fenced code/quote blocks inside of quote
blocks down to arbitrary depths. Code blocks are always leafs.
Fenced blocks start with at least three tildes or backticks,
and the clump of punctuation then becomes the terminator for
the block. If the user ends their message without terminators,
all blocks are automatically closed.
When inside a quote block, you can start another fenced block
with any header that doesn't match the end-string of the outer
block. (If you don't want to specify a language, then you
can change the number of backticks/tildes to avoid amiguity.)
Most of the heavy lifting happens in FencedBlockPreprocessor.run().
The parser works by pushing handlers on to a stack and popping
them off when the ends of blocks are encountered. Parents communicate
with their children by passing in a simple Python list of strings
for the child to append to. Handlers also maintain their own
lists for their own content, and when their done() method is called,
they render their data as needed.
The handlers are objects returned by functions, and the handler
functions close on variables push, pop, and processor. The closure
style here makes the handlers pretty tightly coupled to the outer
run() method. If we wanted to move to a class-based style, the
tradeoff would be that the class instances would have to marshall
push/pop/processor etc., but we could test the components more
easily in isolation.
Dealing with blank lines is very fiddly inside of bugdown.
The new functionality here is captured in the test
BugdownTest.test_complexly_nested_quote().

This should address user reports of huge bankruptcy counts even when
they are relatively caught up. The root issue is that we sometimes
don't mark messages as read for some reason.

This is for the interval while staging is running in VPC and postgres
is not; we can clean up these changes once that's no longer the case.
This also updates test1's IP, which apparently someone forgot to
commit previously.
We're currently running this on prod.

Client objects are immutable and there are very few of them, so caching them in
memory is cheap and saves a trip to memcached.

This makes the notification slightly more conservative as we do our
initial roll out. In particular, it avoids cases like being notified
when you are almost at the bottom of your feed for a message in your
narrow.
