When we get payload from pusher, we usually don't send the entire
record. Initially such records where fetched from server right away to
get missing data. This was done becuase Ember can't tell if given data
is complete or not and just assumes that the record is loaded.
To not fire unneeded request, this code sets incomplete flag on records
loaded from pusher and loads the rest of the data only if needed.
This is working implementation of links on log line numbers. Although it
does the job, it's really hacky and involves overriding some of the
ember's methods (resolvePath, routeMatcher) beacuse currently
HistoryLocation can't handle hash additions in an easy way.
This code should be fixed as soon as ember's router gets more powerful
and gives much more granular control over matching routes.
