Patching now works. bucts can be patched & built.

Modified the function git_project_patch_recursive (in libs/git) to
enable patching with diff files, which uses the new function
diff_patch_file located in libs/common. A generic action script for
bucts is in projects/bucts/. Install/revision/target files are in
projects/bucts/configs/. bucts' merge into the new build system should
be nearly, if not already, complete.
