When compiled with --app:gui, hide consoles

[onionhammer]

On windows if I compile Aporia with --app:gui, and run it, I do not get a console (as expected), however, when I look up a definition or build the project, a blank console window will open up briefly until the operation is complete.

Wow, surprised that this issue is still around.

See readme:

Note: As of 2018 Aporia is considered obsolete. Most of the Nim community has switched to VS Code instead. Feel free to use Aporia, but know that it may not be maintained anymore.
