Sometimes USER objects need to become USER_INT. The attached patch makes it possible.

USER object now can call a method of tslib_cObj to convert themselves from USER to USER_INT. Any existing output will be discarded and they will be called again as a USER_INT object. Here is code example:

        if ($this->cObj->getUserObjType() == tslib_cObj::OT_USER) {
            $content = 'I am running as USER object now.';
            if (!$this->conf['allowCaching']) {
                $this->cObj->convertToUSER_INT();
                return '';
            }
        }
        else {
            $content .= 'I am running as USER_INT right now';
        }

Extension can (and should!) check if it is running as USER or USER_INT. Additionally extensions must have "includeLibs" just like any other USER_INT in their TS setup. But they must be declared as USER.

Patch and test extension are attached.
