Updates to version and path parsing to support windows

[JamesCaska]

Tweaks I found I needed to make it work with windows.

I'm not sure whether I understand the reason for this change. If the "currentPlatform" isn't non-null at this point, we are risking a NPE a few lines above (308). We could however move this logic to the line right after line 306 where we set the text for view.platformLocationField.

Hi, thanks for looking into this.

I also don't fully understand the resolving logic. I suppose both currentPlatform was not being set and was being used later in the dropdown dialog without a null check so I added a last chance check.
Your right about the NPE exception risk and that existed before the change. Maybe the resolvePlatformFromPath should move up before if (platformCoreDir != null) { and also add a null check on view.platformLocationField.setText( currentPlatform.getRootPath().toString() );
