radiobuttons (checkbox-groups) added

[OliverHenniges]

I have recently modified the core-script src/fpdm.php in such a way that it now manages to cope with groups of checkboxes.
At least I think so;)

I'm not familiar with the github-habbits, yet: Shall I upload it here? Maybe after further testing and eliminiting some possible bugs left the modificatiosn might be worth another update.

The example-Form to integrate also contained some ugly umlauts and also a hyphen in the field-definitions. As for this I'd recommend to change the intial regex definition (Line 41) to

$FPDM_REGEXPS= array(
...
"name"=>"//([-#\w]+)/",
...
);
though I think this needs some more testing.

Right now I came across FPDM and noticed that radio buttons are not supported yet. Therefore it would be highly appreciated if you made your modifications available.
I would be up to contribute by testing, however I'm afraid that my skills will not be sufficient to fix remaining bugs.

@OliverHenniges anyway you can share your modified core?
