add new client Koma to the projects page

[komatr]

this project has been worked on for several months, while it still lacks many features, it's probably a good idea to share it and get feedback
please give any feedback and expect continuous active development and handy new features in the following months

Can one of the admins verify this patch?

ListViews just got some improvements!

width of items are managed in a cleaner way, no more manual calculation of widths, which means higher accuracy, better performance and more reliable. Chat messages wrap just before meeting the right scrollbar

wide items in the rooms list and users list are handled: when a name is too long, it's shown with ellipses, because horizontal scrolling isn't a good idea here

the users list also has a semi-transparent scrollbar now

the appearance of chat messages is updated, also more types of messages are shown to the user. (spacing between some ui elements still needs some adjustments)

here's a screenshot, hope you like it!

btw, in the next few days, chat history syncing should be ready
