Checkboxes and radios

[soniktrooth]

I'm opening this issue to track all the things that have happened in the scope of trying to fix the checkboxes and radio buttons.

The following PRs have attempted to fix this:
#207
#235
#233

None of these solved the root of the problem—the main issue being checkboxes inside tables.

Bootstrap adds the following:

.radio input[type="radio"], .radio-inline input[type="radio"], .checkbox input[type="checkbox"], .checkbox-inline input[type="checkbox"] {
  position: absolute;
  margin-left: -20px;
  margin-top: 4px \9;
}

Which is fine for forms but Drupal has a lot of table/form matrix thingys like the permissions page, content page, modules page etc.

There also seems to be an issue with checkboxes/radios inside modals, best reproduced by adding a content list to a panel.

OK, closing all the other checkbox PRs so we can concentrate here.
