Before this commit, the data of all followers of a chatter were
fetched whenever `mail/thread/data` was called. This route is
called when loading the chatter for the first time, and whenever
the chatter must be reloaded.
When there are at most dozens of followers, it's not a big deal.
However, with thousand of followers, the route `mail/thread/data`
may become quite long, which made chatter barely usable with a
long loading.
This commit fixes the issue by showing only 100 followers at once
when opening the follower menu. When scrolling down the list,
it loads data of more followers.
