Temprory fix for removing accumulated messages from RabbitMQ. Currently
snf-ganeti-eventd produces messages that can not be handled from
snf-dispatcher (e.g messages not concering an instance). These messages
are now removed from queue, since they do not concern dispatcher.

Only reset image selection on create view initialization to be able to
keep image selection between subviews transitions.

taking advantage of the urls for weekly graphs that stats service provide.
Refs #1791

More explanatory info for the selection of public keys that will get
copied to the created vm on step 3 of vm create view. Refs, #2462

to avoid conflicts with other applications named urls.

gtools provides common name settings with cyclades app to connect to the
rabbit mq server. It is wise to keep consistency for the default values
of common settings.

- use 'id_rsa' as the filename for the downloaded private key, Refs #2461

It seems that Safari allows popup windows only if the window.open call
is made from within an html element click event context. Otherwise its
behaviour is based on "Block Pop-Up Windows" setting, which when enabled
no notification appears for the user that a popup window was requested
to open.

Since there is no easy way to check the setting value, the action call
changed to use synchronous request. That way the success handler which
calls the window.open method, gets executed within the confirm button
click event context.

In contradictory to this change the user might experience unresponsive
behaviour of the ui when console actions too long to repsond.

The behaviour is limited only for Safari clients.

Update admin's quick install guide to reflect the latest changes,

Do not publish messages for jobs concerning no or multiple instances,
since snf-dispatcher can not normally handle them.
