Configure Travis CI for S3 compiled build deployment

[ryanwarsaw]

Travis CI has been setup and builds are passing, the next step is to request a S3 bucket to be used for storing the compiled build until a new Travis CI build has been triggered.

Tracking S3 bucket request here: MozillaFoundation/mofo-devops#412

Received S3 bucket information, need to determine what will be sent to the S3 bucket and if it will always have the exact same file name, or change with version increments.

I've gotta setup a Gradle task to run specifically on Travis CI that will rename the APK that will be shipped to S3 to something like Jisort-latest.apk, so that its redirect short link mzl.la/jisort will work.

Currently prioritizing a few important bug fixes over this, hence time delays on this landing. Work has commenced however, and I feel good about the direction it's heading in.

The bit.ly link mzl.la/jisort currently points to a very old release build and is still being used on a regular basis, the developmental bit.ly link will need to use a different name.
