macros/graph/PGnauGraphics.pl doesn't use unique name, which can break tests.

[somiaj]

The old checkbox_table and radio_table macros in macros/graph/PGnauGraphics.pl don't use a unique name, so if more than one problem is used with this macro on a test, the answers get confused since the name is fixed. I'm not sure on a proper fix (so opening up an issue), but here is my suggested fix (that works for my testing). I would suggest this could probably be worth an hotfix once a proper fix is found.

The proper fix is to move the macro into deprecated, and not use it.
