Created 3 new tasks:
AddManifestSources
AddRemoteManifestPackages
AddLocalManifestPackages
They are added independently depending on what is specified in the manifest.
They can both be set independently now.
If the bootstrap mirror is not set, it falls back to the apt mirror,
which in turn falls back to the geo redirector.
New phase introduced "package installation" (fixes#114)
Apt source lines are now parsed, this allows to verify the target release of added packages.
All packages (except locales) are now installed *after* bootstrapping (fixes#123)
Added env argument to log_(check_)call
HostDependencies have been refactored a little
MAJOR refactor. The volume is now abstracted into a model along with a partitionmap and partitions.
Volumes and partitions are now controlled via an FSM to ensure that commands are called in the proper sequence.
GRUB can now be installed properly onto loop devices by using dmsetup to fake a proper harddisk.
