v5.2.0

• The -d option was added to specify an alternate cqfd directory.
• The -C option was added to change the working directory.
• Date strings now use POSIX options, eg. for running on macOS.
• Containers are now named cqfd_%user_%company_%project instead of cqfd_%company_%project. This prevents collisions with Docker when several users are using it on the same machine.
• Added a tar_options config file option to pass extra options to the tar command.
• Add support for CQFD_EXTRA_BUILD_ARGS to pass args and options to the image build process.
