rsync upload integration

[rzbrk]

Integrate rysnc update from inside PerlPress.

Possible rysnc arguments: rsync [--dry-run] --checksum --recursive --delete --verbose --compress --progress -e ssh /dir/local user@remotehost.com:remotedir/

Possible PerlPress commands to implement

• list builds - List all available builds in output directory
• rsync [--dry-run] [build-id] - Upload build with build-id (get from build list), optionally as dry run

The credentials for rysnc user, server, remote directory and password(?) shall be defined in ~/.perlpress.conf
