Access FieldPlugin options from within validateContent

[henriksjodahl]

Describe the solution you'd like I would like to be able to access FieldPlugin options from within the validateContent function.

The reason is i've got a plugin that selects objects, and i was thinking about having an option that states if it should be an single or multiselect. And if multiple, the validation creates an array, if single its just a string.

Describe alternatives you've considered ...
