Fix #136 -- Add dependent-field support to formsets

[Ombental]

I labeled this as minor because I didn't take into consideration all use cases but my private one, though I do think it answers most of the needs. this is django admin oriented

Hi @Ombental,

Thank you for your contribution. I appreciate your help. It looks like a promising start. I left you a small suggestion. Besides that, I'd appreciate it if you could add a test. The selenium setup is a bit tricky. Don't hesitate to ask for help, regarding the tests.

Cheers!
Joe

I believe you can simply this a little and drop the else branch, like so:

Suggested change

	var formValue = $('[name=' + dependentField + ']', $element.closest('form')).val();
	// This is for inlines, I checked this for a specific case
	if (formValue === null || formValue === undefined) {
	var newFieldName = $element[0].name.split('-', 2).join('-') + '-' + dependentField;
	var formsetValue = $('[name=' + newFieldName + ']', $element.closest('.form-row')).val();
	result[dependentField] = formsetValue;
	} else {
	result[dependentField] = formValue;
	}
	var formValue = $('[name=' + dependentField + ']', $element.closest('form')).val();
	// This is for inlines, I checked this for a specific case
	if (formValue === null || formValue === undefined) {
	var newFieldName = $element[0].name.split('-', 2).join('-') + '-' + dependentField;
	formValue = $('[name=' + newFieldName + ']', $element.closest('.form-row')).val();
	}
	result[dependentField] = formValue;
