copied license files to repo root for visibility
fixed flipped doc in screen
moved process management from shell to kernel and exposing it via new `process` api, removes some nasty cross dependencies
synchronizing filesystem component and making open/read/seek/close limited direct calls, reduced default max read buffer in turn. this should give better performance when reading many small files; made fs.close direct without limit to get rid of the ugly file handle gc workaround involving a timer
some cleanup; moved language specific file system (lua/rom) to lua architecture
fixed file system labels not being saved. oops.
