Remove unnecessary capitalization
Rework the "Our idea is" paragraph
Trim down the "Framework" list.

- Add "Written in ObjC ARC"
- IMHO it's unnecessary to say "high quality api docs" as the link to the docs is clearly visible in the menu
- Removed "UUID use" and "favour JSON"
Revision control -> version control. Remove "Semantic merging" but describe the merge system in more detail, mention pluggable merge strategies
Add "for Objective-C" to first paragraph
