[PATCH 3/3] cg-patch: Add -d option to apply patch directory

[Jonas Fonseca <fonseca@diku.dk>]

It tries to do some minimal sanity checking on the individual patch
files, to ensure that they are created with cg-mkpatch. This includes
checking that the filename starts with [0-9]*-, the patch is non-empty,
and it contains author information from git-cat-file output.
