Some stylistic fixes

Now the background color is dark gray, the same
as plugins. Also managed to render the dtgtk_labels
correctly now.
Authenticating twice + pwstorage

Now authenticating before exporting and uploading
to make sure it'll be accepted. Pwstorage is implemented
as well.
Not saving changes locally

Instead shipping name and description as
vars that are replaced in the dtstyle file
server side. Ugly, but better than messing
with our precious database.
Added option to save changes locally

Changes in name and description that is.
