include current Android Locale in Debian setup

This sets the language on the Debian install based on how the language is
set in Debian.  It will only generate the locales on install, but it will
always set the current locale in start-debian.sh.  If the current locale is
differen than the locale at install time, the user needs to manually gen
the current locale in Debian.

add note about getting cdebootstrap package from snapshot.debian.org

Since we're using the most recent version, whenever it is updated, the
previous version disappears from the main archives.  Luckily, it can still
be found in snapshot.debian.org
download cdebootstrap from snapshot.debian.org in case the version gets bumped

snapsnot.debian.org keeps archived versions of old packages, while the
mirrors do not.  So if 0.6.5 gets released, then 0.6.4 will disappear from
the mirrors, but still be available on snapshot.debian.org
move loading of Install Log into AsyncTask
clean up whitespace: tabs --> 4 spaces; remove trailing whitespace
set indeterminate progressbar when loading the install log into the view
include cdebootstrap deb in git, in case this version disappears

For anyone who wants to verify that this is using the original, they can
rm the included .deb file, and it'll be downloaded again.
