[Localization] Pootle: update function

[Korakurider]

Hi
What "Update" links in Pootle's "editing functions will do?
When clicking "Update" for some activities I got error like
----
  [GIT] pull failed (['git', '--git-dir',
u'/srv/pootle/checkouts/honey/labyrinth/.git', 'pull']):
ssh_exchange_identification: Connection closed by remote host fatal:
The remote end hung up unexpectedly
----

It would be great if it could replace periodic pulling POT...
