Remove "ng" action deprecation warning

[noresources]

What seems to be the problem?
Registering an action ending with "ng" (such as "binding") raise a warning.

binding' has been deprecated; use 'bindi' instead

What have you tried so far?
Simply removed related code in function m.prepareAction() and function action.get(name)

How can we reproduce this?
Register an action with a trigger ending with "ng"

What version of Premake are you using?
master

Noted. I'll try to address this before the next release (but would be happy to accept a PR for it in the meantime).
