Updated Build

- Made the newest versions of plugins.
- Removed unused/unneeded gradle.properties
- Removed unused/unneeded maven publishing tasks.
- Manifest File Cleanup
- Fixed failing test.

Note: minSdkVersion was bumped to 7. This was done in order to use the fest-android. I don't really see this being an issue, but a workaround can be found if you think it will be.
is an updated dependency requiring a minSdkVersion of 7?
