Bug 512550 - Hide C and C++ Project Wizards and fix canFinish().

Hides the C Project and C++ Project wizards in the wizard shortcuts
for the CPerspective. Also removes them from the shortcut list
in the project navigator. Adds the C/C++ wizard that was missing
from the project navigator.

Also makes sure we pass along the call to canFinish from the new
wizards to the old ones.
