ZF-3730: <form> should not render id attribute if ID is not present (invalid XHTML)


There is no reason why every


form> should have own unique ID

If I dont specify ID for Zend_Form then form is rendered as


form id=""> which is also XHTML invalid



Scheduling for 1.6 final release.

Already fixed in trunk and 1.6 release branch in previous round of fixes.

Updating for the 1.6.0 release.
