Breaking Changes in the upcoming version

[Mario]

@Developers: I used the opportunity to simplify/unify the behavior of some endpoints as noted in the release notes.

For example, all /resultwindow and points now either return 200OK (success) or 500 (server error) with additional data about the error.
Before the endpoints sometimes returned 500 or 200 OK with a result != "ok". Bad decision at design time.

I have updated all apps and sample apps to handle the new return values, where needed. If you have used endpoints or IMatchLib wrapper methods modified for this release, please do the same.
This change should affect only very few apps.
