Move out common message event content classes

ImageContent is usable outside of m.room.message (in particular, m.room.avatar
uses the same structure for content. And EventContent::Base is very suitable to
derive from even for standard event content structures (such as in room name
events), let alone non-standard ones.
Also, renamed MessageEventContent to EventContent (for obvious reasons).
