Show notification settings

[dbrgn]

Make it possible to enable/disable desktop notifications.

I have implemented this feature.
But I will wait untill the pull request #110 is merged into master in order to integrate the notification settings into the settings and to store the preference in loacal storage.

nice to see someone already building upon that :) , i think until the pull request #110 can get fully accepted into master it will still take some time because of the Theming thing(issue #9). I could try to get the changes for the settings menu into a separate pull request. @dbrgn Or does it make more sense to make a WIP branch for settings features ?

@FloThinksPi maybe you could extract the (empty) settings dialog to a separate pull request, if you're well-versed with cherry-picking / rebasing :) We could then merge that to master so that @IndianaDschones can integrate the notification settings.

@IndianaDschones the (empty) settings dialog and the settings service have now been merged to master!

[IndianaDschones]

@dbrgn I think we can merge the notification settings today. I´ll performe some tests and if everything goes well, we´re ready to go 😄

@IndianaDschones btw, I did some small changes to notifications in #108. Shouldn't affect you though.
