Bug 381171 - CreateRequest should extend LocationRequest

The class CreateRequest in the org.eclipse.gef.requests does not extend
the LocationRequest class from the same package, instead of subclassing
it simply reimplements the whole functionality.

Closes https://bugs.eclipse.org/bugs/show_bug.cgi?id=381171
