_JAVA_OPTIONS and sane TERM
 - Set _JAVA_OPTIONS to force use of properly anti-aliased fonts, as
   well as setting the default theme (which may break certain apps)
 - Set TERM to 256 color terminal if we can.
Hopefully a more lightweight X startup
 - Try to start X and make it honor the XDG_CONFIG standard.
 - First attempt with tiling window manager i3 (use termite terminal
   with that manager).
