Update GUI via Asynchronous thread

Ignition

OK. I’ve poked myself with the futures idea. Grab the latest version of later.py, then try this:

def asyncInvoked():
	# do something in the background
	shared.later.callLater(system.gui.messageBox, "Please Press OK").get()
	# do something after OK is pressed

system.util.invokeAsynchronous(asyncInvoked)

Note the use of .get() to wait for system.gui.messageBox to complete.

This updated later.py includes an emulation of invokeLater for gateway scope. Untested and unsupported!

Edit: Realized the invokeLater emulation should only use one thread. Fixed.
