Refactor

[Jawnnypoo]

This PR is very similar to https://github.com/parse-community/ParseTwitterUtils-Android/pull/36

• Update packaging of library to com.parse.facebook instead of com.parse to avoid conflicts
• Remove bolts direct dependencies in favor of transitive dependencies through the main SDK (Facebook SDK no longer uses bolts)
• Update broken links in README (guide, license, coveralls)
• Point to main module contribution doc
• Distribute with JitPack for easier distribution
