Set PHPTAL output mode based on view doctype declaration

[xorock]

PHPTAL has 3 constants

    const XHTML = 11;
    const XML   = 22;
    const HTML5 = 55;

which are responsible for generating the corresponding closing tag for specific doctype.
Maybe You could add option for setting correct output mode being in relation with resources.view.doctype option?

Thank You in advance.
