Implement Mode.ANIMATED_THUMBNAIL used for autoplaying animated images

Browse Source 
This patch introduces a new `ImageContentRenderer` mode used for
autoplaying animated images. The mode shares url resolving semantics
with `FULL_SIZE` and `STICKER`, as such not just fetching thumbnail data
but shares sizing semantics with `THUMBNAIL` (scaling by image height).

This change fixes animated images not playing in cases in which only a
static thumbnail would be loaded.

This new mode will only be chosen if the message content is actually a
playable image, as such limiting bandwith usage to the required amount
by avoiding to load normal images fully (still fetching animated images
will increase bandwith usage as a whole of course).
