[GSoC] Improve user experience with CMIS – Weekly report #10

This week mainly I was looking for bugs. My commits:

* When user aborted an authorization to the service, listbox still was
showing service's name. Now in this situation a listbox field will be
empty

* I improved save mode. Now the file name entry is not cleared when you
select folder.

* “Wait” mouse cursor while expanding node in the tree

* Title bar didn't contain any information that opened file is loaded
from remote service. I've added “(Remote)” after its path.

* I've increased a speed of loading a folders content. We had two
widgets containing the same data (FolderTree and SvtFileView). Their
work was independent and remote directory was read two times. I used
cached data from SvtFileView for filling the tree, and load time was
decreased two times.

* CMIS: When two different users wanted to use one repository, session
was cached only for the first. We was looking for cached session with
key: URL + RepoID, so for second user a login box didn't appear and was
used the same session. To fix this I added to the key also an user
field.
