Land of Karchan

ell, the server move did not go as planned. I hit a few problems, and decided enough is enough.

I will try and test more.

I did manage to put up a new release, but it's a boring one (from your perspective).

I'll add release notes when I have the time.

Highlights

alternate docroots: alternate docroots allow me to put up static files and map them to urls. It means I no longer have to deploy wars containing images and things. Also helps the Let's Encrypt challenge
"strict" mode: enabled "strict" mode for karchanadmin and karchanpersonal which was a huge pain in the ass. It means the compiler will check much much more, and though it helps to catch errors, it also meant for me to rigorously change a lot of code. So let me know if I broke something.
idle users: created an IdleUsersService. This means I won't have to store and change the timestamp when a person last issued a command in the database anymore. However, this information is volatile and lost when the server is rebooted.
streaming: Updated the adminpages: retrieval of all thingies for the admin pages can be a lot (for instance, all rooms), so decided to use a scrollable cursors.
