Fix for PyQt's _triggered() functions being double called.

gistfile1.py

# Instead of this...
def on_actionBuild_Zip_triggered(self):
	[...]
# ... We do this.
def on_actionBuild_Zip_triggered(self, checked=None):
	if checked is None: return	# Makes certain the action does not get ran twice.
	[...]

# This ensures that when it does get called twice, the second time will be ignored immediately.
