Group strings and remove unused resources
Before I grouped the strings, I removed unused resources as well to not group things that are not being used anymore.
The grouping tries to follow a normal usage lifecycle of the app where the user works their way down the navigation drawer and explores all features in one area.

This commit refactors the code for sharing forums,
so it can be used for sharing blogs as well.
It does not yet include code for responding to blog invitations.
Micro Blogs UI
**Attention:** This MR includes several other commits which are supposed to end up in separate MRs. I suggest that you review **per commit**. Once the first two commits have green light, I can split out the other commits into other MRs. This way I don't have to work myself through a long rebase chain every time I make a change to the bottom MR.
This MR is full of commits that introduce features that we will not be using initially. The last commit implements the Micro Blogs UI on top of the framework the first commits establish and hides/disables all future features for now.
I suggest we merge this as is and clean things up later when we have a clearer idea what features we will be doing eventually.
