Fix #568 with ENV var workaround
EDMC.py would break due to an import chain that ends up in theme. Theme does a whole bunch of work to setup our GUI for EDMarketConnector.py, but it does this on any import, which will fail spectacularly if there is either no DISPLAY var set or no X11 libs available on our machine at all (as a sidenote this means it probably also breaks on a wholly wayland install). This fixes the issue by adding a check for an environment variable on import of theme. This can and WILL break if the env var is set and EDMarketConnector.py is used, but if you do that its your own fault.
