Update Android app configuration

- Added uses-feature flags in line with SDL app. Hopefully this should:
  - fix handling of right mouse button
  - make VCMI available on TV's running Android - these devices don't
have touchscreen feature, which is added as required by default
- Unified AndroidManifest formatting - was mix of tabs & spaces
