Applying slightly modified patch from jnqnfe <jnqnfe@gmail.com> to show correct win32-loader ico file on windows (Closes: #772781).

Historically we tried to have all necessary information
in bug reports, such as version of certain packages used
during the build.

In reality, the only interesting package is debootstrap
on the host system - everything else is taken up from
the mirror from within the chroot and is noted in the
build log.

Users building non-chrooted will have to collect their
information by hand anyway, so it's better to remove
anything but debootstrap.

Updating wget dependency in installer_debian-installer to look for wget on the host system rather than the chroot.

debootstrap is the official tool to bootstrap debian,
cdebootstrap has had the one or other bug making it
broken for times during the release cycles.

The extra effort of supporting both debootstrap
and cdebootstrap is hardly worth it since the bootstrap
stage is cached anyway.

Address "should check that we're building on debian through e.g. a 'derivative-is-based-on' variable or somesuch" fixme.

If a local repository path is given as a mirror URL lets bind it into the
chroot. The local repository will be unmounted while processing "remove" or
latest by the exit function.

Comments in package lists used to work in live-build 3.x (although
possibly only as a side-effect of some other logic) and being able to
comment package is a useful feature (to explain why some packages are
included and to make it easy to uncomment some lines to add more useful
packages).

Somewhat fixing sysvinit and casper legacy support, slightly improved patch from Rui Miguel P. Bernardo <rui.bernardo.pt@gmail.com> (Closes: #772522, #772651).

This however will still not work properly building upstart based
images but they have been broken/unsupported anyway since a long
time.

Fix typo in variable name (LH_LINUX_FLAVOURS instead of LB_LINUX_FLAVOURS) in installer_debian-installer script, affecting the armel architecture (Closes: #770796).

Correcting typo in apt.conf.d directory name, thanks to jnqnfe <jnqnfe@gmail.com> (Closes: #771392).

Correcting stage name check in chroot_includes, thanks to jnqnfe <jnqnfe@gmail.com> (Closes: #771377).

Avoid failing to autocreate live.list.chroot in lb config when using --clean, thanks to jnqnfe <jnqnfe@gmail.com> (Closes: #770637).
