Add VIEW indent to enable resume/start with documents.

This registers Coffice in Android for ODT mimetypes. From
now on when executing a ODT file Coffice will be offered
as choice to open that ODT file with.

It also makes resume proper working. That means if Coffice
was suspended by Android it will resume now with the
previous displayed document (but not the proper flickable
contentX/contentY yet).

While on it I also fixed a stupid typo in KUrl that
resulted in an infinite loop and made openFile assume
it operates on local files. Still missing is proper
error-handling to display that/what went wrong when
loading. To do for later.
