Show warning if config file can't be written due to permissions issues on linux

[ghost]

Hi,

today we had a hell of debugging a users problem on the forums:

https://forum.owncloud.org/viewtopic.php?f=14&t=13352

Seems that something was going wrong and the ownership of the .local/share/data/ownCloud folder was changed during some unknown reasons.

Expected behaviour

Show a proper message if the .local/share/data/ownCloud/owncloud.cfg file can't be written.

Actual behaviour

The configuration of the client fails. No proper message about the wrong permissions is shown.

Something similar was already reported some months ago at: #148

I encountered the same behavior today when my ~/.local/share/data directory did not have write permissions --- the ownCloud client silently failed to write its configuration out, despite the interface letting me browse around. So this issue remains in client version 1.5.2 on (Ubuntu 13.04) Linux.

@RealRancor Is still happening in the latest version?

@lmaestro
Sorry this was just a report of a user having this problem at the forums but maybe @williballenthin can answer you this.
