First bulk removal of I/O Extended stuff

At the point where the app compiles. Will still need more in-depth changes, probably, as I've only removed all Livestream-related strings, activities and code branches that prevented from building.
Removed LiveSession field and code

Bumped ContentProvider DB version to 1.2, so that it will be recreated when updating. The new DB version lacks the LiveSession and LiveSessionURL columns (or should, if I haven't missed it somewhere).
