Updates Composer File
Initial stab at POSTing generated docs to a waiting doc-management script.

Intended to feed ZIPs of PHPDoc and PHPUnit code coverage directories to https://github.com/beporter/docs-manager.
Added doc note about `curl` dependency.
Force removal of old zip file.
Removes the need for an intermediate ZIP file that only caused problems.
More WIP.
