FIX - Correction of new hook PR

This PR corrects the PR for adding a new hook. I made the mistake of setting the text_info replacement to $reshook == 0, which is the default value for reshook, which always replaced the given with empty when the hook was not in use.

i made an error by validating a new hook into an already released branch. i revert it.
You can submit the hook into develop branch.
Also the fix is not correct. We should have

if ($reshook == 1) {   // We replace
						// for add information
						$text_info = $hookmanager->resPrint;
} elseif ($reshook == 0) {     // default action, we add if there is something to add
						$text_info .= $hookmanager->resPrint;
