Figure out how to get gif to work with data uris

For some reason dealing with gif images are tricky using Glide (the library we use for image rendering).

Currently it mostly works, with exception of an animated gif being rendered from a data-uri. Need to fix eventually

Start by reproducing the animated GIF data-URI case in the Android app and trace how Glide receives and renders data URIs. Compare it with the existing working GIF cases; done means animated GIFs supplied as data URIs render correctly without regressing other GIF handling.
