Currently, this function is worked for currrent page only:
called as {{#translation:}} and is returned "/code", if page is translation, or empty string otherwise.

Proposed update for ability to using this function for specified target page, as {{#translation:pagename}} or {{#translation:namespace:pagename}}.

This will be useful for eliminate widely used templates {{ifTranslation}}/{{ifNotTranslation}}, {{TNT}}/{{TNTN}} and {{Ll}}.

Taret result for my proposal:

1. if current page is translation, and {{#translation:}} is returned "/code", then {{#translation:pagename}} should be return "pagename/code" (if this page is exist) or "pagename" otherwise;

2. if current page is _not_ a translation, and {{#translation:}} is returned empty result, {{#translation:pagename}} should be return "pagename"

Note: maybe this should be separate magic word, as '#tlink' or '#tl' (or simple create these short aliases for this function)?
