2nd review:
	- removed error catching in git service methods
	- removed modal spinner in clone repo wizard view
	- added data provider for remotes list in select repo component
	- removed dead code in clone repo wizard view
	- added visibility condition for clone repo action: for empty repo node
review 2:
	- changed view states syntax to AS3 rules
	- used vgroup instead of vbox in clone repo wizard view
	- modified visibility condition for clone repo action; works for
existing git repos in folder (clone action does not appear in git
actions menu); could not be tested for empty folders
