Client changes:

• Added the rebuild command and the --ignore-rebuild-deps and --ignore-external-rebuild-deps flags. See the man page for more information. (RMK-783)

• Make sure group recipe source files (group scripts) are handled correctly when building .recipe files. (RMK-785)
• A change in the signed key handling in conary 2.0.7 caused the installation of signed packages whose keys are not already in /etc/conary/pubring.gpg to fail in rmake. Signed updates now work in rmake with conary 2.0.7. (RMK-702)
