Reorganize the tree for easier and better handling.

- Template helpers have been moved to templates/helpers. - Documentation to docs/. - Common scripts have been moved to utils/sh. - Fixed install-destdir when executed via chroot. - Added a build-pkg target that builds a binary package. The package must be installed into destdir before using. - Misc tweaks and fixes. --HG-- extra : convert_revision : 0896e8f24bb7592116aaf77ae9c776033818a3d8
