Working prototype

There is very little responsibility to the preamble to v1 of this repository; the server script simply calls PHP's inbuilt server using php -S 0.0.0.0:8080, with a few settings wrapped using Gt/Cli.

There are plans for implementing a PSR compatible Http Server in this repository, but until then, no further features are planned in the v1 release, so unless any bugs are detected with this implementation, a v1 release will be made when the next product running WebEngine is complete and deployed, as another real-world test.
