FormField/Radio Template static class prevents inline display

[stokkeland]

In Template File ui/template/semantic-ui/formfield/radio.html line #2 contains

class="{$class} grouped fields"

Where the grouped class makes it impossible to have an inline display of radio's - and as far as I can tell removeClass is not capable of removing from the template itself.

I am planning to suggest a fix and submit a PR, but it may be a while till i can get to it, i have not adopted 2.0 yet.
The fix could be as simple as removing the class from the template, but i assume many are dependent on this functionality already, so it should likely be accompanied by it being added as a default class for this field type, that can then be removed with removeClass, or perhaps even automagically replaced if addClass('inline') is performed, such magic should then allow something like this in model:

$this->addFields[['standard_payment_terms', 'ui'=>['form'=>['Radio','class'=>['inline']]], 'values'=>[0=>'No',1=>'Yes',9=>'Maybe']]]
