To continue this formatting madness, here's a tiny patch that adds
unified formatting for control structures like if and loops as well as
classes, their methods and anonymous functions. This basically forces
the constructs to start on the same line. This is not exactly what PSR2
wants, but I think we can have a few exceptions with "our" style. The
starting of braces on the same line is pracrically standard for our
code.
This also removes and empty lines from method/function bodies at the
beginning and end.

When installing an app from the appstore the `\OC_App::getAppVersion` code is triggered twice:
- First when the downloader tries to compare the current version to the new version on the appstore to check if there is a newer version. This protects against downgrade attacks and is implemented in `\OC\Installer::downloadApp`.
- Second, when the app is actually installed the current version is written to the database. (`\OC\Installer::installApp`)
This fails however when the version is actually cached. Because in step 1 the cached version will be set to "0" and then be reused in the second step.
While this is probably not the cleanest version I assume this is an approach that is least invasive. Feedback and suggestions welcome :)

We should verify the app versions when installing a new update, otherwise this could result in downgrade attacks when an attacker just copies the old signature.
Plus it prevents the case that in case of a bug in the appstore actually an older version gets installed.
