Subject: [PATCH] Add suggestion from PR #237 to support custom rows definition
 for translatable fields and have it use that when the user is editing the
 translation text. To use, specify "rows=3" somewhere in the translation
 comment, i.e. `__('text'); // rows=3`. Also added support for `type=name` in
 the comment, that lets you specify what Inputfield type to use. To use,
 replace the `name` part with "text", "textarea", "email", etc. Or if you
 prefer you can use the full Inputfield name, i.e. InputfieldText,
 InputfieldTextarea, etc.
