Make the user's custom fonts available to Koreader.
Handle both SyV & upstart properly
Handle the 'no framework' mode on upstart systems, even through KUAL.
Plug the 'no framework' mode to the KUAL extension.
This is a mix of some stuff I completely forgot I had in my tree, and
what Aeris did for

Tested on a Touch.
And it will fix the blank screen bug and the first-time-launch-mess-up bug introduced by
kpvbooklet. Users who use KUAL exclusively will not be affected and pillow is disabled
each time koreader is launched. For those who have installed both kpvbooklet and KUAL
and use both launchers alternatively, it's better to reset the booklet counter with the
command `lipc-set-prop -i com.github.koreader.kpvbooklet.timer reset 0` before launching
koreader with KUAL. Otherwise, pillow might not be disabled.
