Support croutoncycle commands via websocket
Add basic chroot listing and switching to the extension

TODO: croutoncycle should check version and then write 'C' to the fifo.
Only show one of the windowlist or the "connected" status
Hide log behind checkbox, and move disable button.
Extension should still display "connected" with old chroots
Bigger font size.

But, seriously, we need some UI redesign.

find-nacl: RIP hexdump, long live od!
croutoncycle can open xiat windows.
