_editorPathSuffix behaves inconsistently across all Platforms

Hi Adam,

Is there a reason for _editorPathSuffix taking cmdVersion parameter into consideration only on Windows?
I can see those executable variations on Linux (screenshot below).
I'm not sure how these executables work and if they're also supported on MacOS and on Installed builds.
Anyway, should be pretty easy to fix. I can quickly change it. Let me know what do you think.

ue4cli/ue4cli/UnrealManagerWindows.py

Lines 76 to 77 in fed71c1

	def _editorPathSuffix(self, cmdVersion):
	return '-Cmd.exe' if cmdVersion == True else '.exe'

ue4cli/ue4cli/UnrealManagerDarwin.py

Lines 36 to 41 in fed71c1

	def _editorPathSuffix(self, cmdVersion):
	version = parse_version(self.getEngineVersion())
	if version < parse_version('5.0.0'):
	return '.app/Contents/MacOS/UE4Editor'
	else:
	return '.app/Contents/MacOS/UnrealEditor'

ue4cli/ue4cli/UnrealManagerLinux.py

Lines 48 to 49 in fed71c1

	return ''
