final touches on Forms

system - removed trailing unused form-html
Form - set proper width for submit-button column
Element - support returning raw-list for Inputs
Group,Input - renamed getColumnWidth to getWidth
Input - make setWidth consistent with Form->setWidth, directly add
  proper class to column
