Added osg:State:have_applied_mode(mode) and have_applied_attribute(type) to make it

easier to specify which modes and attributes have been modified without
the user requiring to know to what value, or to have an equivilant attribute
to pass to the have_applied_attribute method.  The original have_applied(mode)
and have_applied(attribute) methods have been renamed have_applied_mode(),
have_applied_attribute() as this was required to prevent the mode and type
values colliding during compile (it was causing a compile error when the method
names were the same.)
