[Maposmatic-dev] [PATCH 3/6] Abort suggest Ajax query before starting a new one

[Thomas Petazzoni]

The .abort() method of Ajax requests allows to abort the in flight
Ajax request. We use this to abort the previous Ajax request before
starting a new one, which avoid the problem of having old Ajax request
replies coming *after* new Ajax request replies.
