requirements.txt for plugins
I think it's better to add the ability of having requirements.txt for plugins instead of relying on the requirements.txt file on this project.
One of the reason for this is EE plugins and probably custom plugins made by the organization that uses GitMate, It would be far easier and better to just declare the requirements needed by the plugins instead of adding all of them to the requirements.txt which can also mean CE version of GitMate won't contain EE dependencies thus removing the bloat on CE images.
