Ghost Kernel

I wrote a small calculator to test the UI interface of the window server. The application is all implemented in client side, using the API that the server provides.

It only does integer calculation at the moment though, because I was too lazy to implement strtod. :D Here's a little video of it in action. See the source code on GitHub to get an idea of how the UI API is used here.

The latest changes overall are a lot of improvements in the client-windowserver protocol, a login screen and some cleaning up in the terminal (occasional deadlocks fixed). Currently working on making the ramdisk filesystem writable to have a temporary storage, fixing the new scheduler implementation on multi-core systems (has some bugs), and then implementing a desktop application with nice little icons.
