Feature add android sample

Thank you for Garapon Hackathon.

I add Android Sample application to using Garapon4J library.
However, I can not merge from main library(Garapon4J/project/src/me/gizio/garapon4j/).
This android sample app is included Garapon4J library(Garapon4J/sample/Garapon4JAndroidSample/src/me/gizio/garapon4j) which is changed General DefaultHttpClient from HttpClient4.3(Apache commons).
This is added to new issue.
