ZF-3028: enctype for <form> has to be set via setAttrib. setEnctype() is missing


enctype is important Zend_Form attribute, thats why I believe that it deservers own method. Possible values should be inside constants.

i.e. $form->setEnctype(Zend_Form::ENCTYPE_MULTIPART)


Please evaluate and categorize/assign as necessary.

Scheduling for next minor release.

Added in trunk with r10703 and merged to 1.6 release branch with r10704.

Updating for the 1.6.0 release.
