if the cursor is before the first mention => insert it correctly
if the cursor is after the last mention => insert it correctly
if the cursor is between those two => insert it at the end of the
composition box
Also:
- New schema version 8 with video/image thumbnails, screenshots, sizes
- Upgrade messages not at current schema version when loading messages
to show in conversation
- New MessageDetail react component
- New ConversationHeader react component
Biggest changes forced by this: alt tags for all images, resulting in
new strings added to messages.json, and a new i18n paramter/prop added
in a plot of places.
Another change of note is that there are two new tslint.json files under
ts/test and ts/styleguide to relax our rules a bit there. This required
a change to our package.json script, as manually specifying the config
file there made it ignore our tslint.json files in subdirectories
