When trying to use the debug proxy in Testing code I hit multiple problems resolved in this merge request. Due to changes in the applications CLI this is a breaking change.
The xdebug_port and context parameters are replaced with a single xdebug parameter which has the form "Context:Post,Contex2:Port2,..." e.g. "Testing:9001,Development:9003". With this change the tests can be configured to use another xdebug port and the proxy can then use the same context the tests use to determine class names, while the port the ide listens on stays the same.
There are further small changes (more logging, slightly different Dockerfile to speed up repeatedly building the container) and some changes in the actual mapping code which were required on my machine to ensure the file paths are resolved reliably.
The README.md is not yet changed. Before changing it I wanted your feedback on this change in general and maybe adapt it if required.
