Wagon 1.0.1 parameters change

Was really confusing to follow this docs for wagon 1.0.1 which doesn't work with this option anymore. Figured out after a while that it pushes all resources if no option has been specified.
Move shorter syntax description lower

Parameters are not used in the push all command anymore - moved the short syntax to pages example
