[GSoC] Improve user experience with CMIS – Weekly report #7

My changes from this week:

* checking if file exists (user could type wrong file name) in the open
mode
* added “Open remote” entry in the dropdown menu of an “Open” toolbar
button.
* added “Open remote” button to the Writer's and Calc's standard toolbar
* added dropdown  menu to the “Save as” button (now it is a split
button) and “remote file” entry inserted to it. This entry executes
new .uno:SaveAsRemote command.
* default focus is set to the file name field, default button is
Save/Open
* auto extension in save mode
* now only one error appears after failed authorization
* fixed bugs:
        - crash sometimes after double click on file view
        - crash after pressed “Enter” on keyboard
        - now if user cancels authorization, login dialog is not shown second
time
        - repository id is remembered if user don't change it in edit mode

Finally my dialog can save files too :)

To do next:
- add separators between groups (apps, services, protocols) in service
type listbox
- save mode: question if file exists
- get feedback from designers
