To support federated rooms, capabilities have to be checked from the room which now also has capabilities.
If room is not federated, capabilities fromuser are still checked.
This is why CapabilitiesUtil had to be refactored to accept SpreedCapabilities which can come from room or user.
Other than that, many other changes were made as a result of this change.

Fresco is replaced with Coil everywhere to make it possible to set 'minSdkVersion'
to 23. But Coil is not used directly to avoid splintering the dependency
everywhere in the code. Coil is wrapped by extension functions for 'ImageView'.
Some shared functionality is moved from 'DisplayUtils' into the
'ImageViewExtensions'.
The exisiting initialization of Coil has also be changed. The usage of the self
initialized OKHttp client is removed. If this one is added the
caching of the http client is used by Coil additionally to memory and
disk cache.
