[android] Update parse dependency to 1.4.0
First stab at handling push notifications in Android.

We only publish through the Play Store, so use Google's standard push receiver
instead of Parse's custom built one.

Upon clicking a notification, the app should open to the right page, whether
that's Bulletin or Newsletter is determined from the "channel" extra.
Get rid of an unnecessary level of nesting.
Added andoid push based on intents, actions and titles.
[ios] Added background fetching for remote notifications on iOS 7.
[cloud] Send background content-available: 1 on push.
[cloud] Send background content-available: 1 on push.
[cloud] We can’t do query targeted pushes combined with channels.
[ios] Logging on background fetching.
[ios] Added neat cocoa pods trick, using the acknowledgements in the settings bundle.
[ios] Removed hpple dependency.
[ios] only build for the active architecture during debug to prevent workspace build weirdness…

Pods was rejected as an implicit dependency
[android] Use gradle-plugin 0.8, Studio 0.4.3.
Merge branch 'master' into feature/parse-push

Conflicts:
	Android/Sebastiaanschool/Sebastiaanschool.iml
	SebastiaanCloudCode/cloud/main.js
[ios] Tweaked appearance of navigation bar on mail screen.
[android] Add missing manifest entries to make parse push work.
Changed Android intents.
[android] Various push notification things:

- use Actions instead of Channels to determine which page to open.
- use a small, white push notification icon, conforming to the
  style guide.
- drop the `packageNameSuffix` for debug builds, because it inter-
  feres with the push message receiver component.
