Fix: disable dependency on Gatway module

- manual install of plugin throws a `Plugin Coder Gateway
  depends on unknown plugin com.jetbrains.gateway` warning.
- it seems to be a Gateway issue so I've raised
  https://youtrack.jetbrains.com/issue/GTW-1528/Plugin-depends-on-unknown-plugin-comjetbrainsgateway
- resolves #39
