chore: Add grunt-time plugin
chore: packages in versioned directories
chore: Add s3 task

This task will upload the current packages for the current version
(located in `_dist/{VERSION}/{PACKAGE}.zip`) to the releases
bucket.

For this to work you need to set valid environment variables for
`AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY`.

Current packages are:

`(jquery.)([s3|azure].)fineuploader-{VERSION}.zip`
chore: Upload new releases to release bucket

A new release is automatically uploaded when a travis ci build to master completes
(as long as it is not a pull-request). Also the S3 keys must be in travis.yml
chore: Add encrypted s3 keys for travis

SECRET_ACCESS then ACCESS
style: Forgot about the style :cop:
chore: Upload `develop` branch zips

For initial testing purposes, mainly.
