Fix group_connectors option not working

[Swij]

Closes #23

Hi @Swij thanks for contributing. I like what you are going for here.

I would make two suggestions for now:

1. Not all connectors are in Connector: library

Instead, something like if self.getLibName.lower().contains('connector') and other.getLibName...

2. The library symbol names should match (even if they have been renamed in the schematic

example: Say you have a connector named "Motor" and another called "Battery" but they are both instances of Connector_Generic:Connector_1x02 then they can be matched.

counter example: If one connector is Connector_Generic:Connector_1x02 and the other is Connector_Generic:Connector_2x20 then they should not be considered equal.

In these cases the Connector_1x02 part would have been renamed to something like Motor but the libPart reference should still be accessible

Hey @SchrodingersGat, thanks for the quick feedback!

1. Fair point! I've added a fix for that.
2. Isn't that up to comparePartName() to decide? As long as "Part" is added to GROUP_FIELDS it should never group two connectors with different symbols.

You're correct re: point 2!

Otherwise looks good. Thanks for contributing!
