The old mentionMap was very inefficient to build and scaled badly with
room member size. This resulted in noticable lag when sending any message
in a large room, no matter if it contained a message or not.
Now, the algorithm is severly optimized and mentions (and emotes) are
only loaded when actually used.
Previously only the first child node of a spoiler was considered to
determine if there should be a spoiler reason. This was, unfortunately,
incorrect, as soon as e.g. the reason had more than one space. This is
fixed by properly iterating all child nodes to search for the reason.
This PR adds support for nicer mentions in markdown: You can now
fetch the mention string of a user with `user.mention` which is
human-friendly (typically contains the display name), which will get
properly pillified upon passing through the markdown parser.
