[WS] Implement basic workspace system

* get_started.py sets up a new workspace in a project folder
* build.py builds the project using info from Tupfile.lua
* run.py moves compiled program into kolibri.img and boots qemu on it

Only supports very simple programs for now (tested on few demos).
Only tested on Windows for now.
