Remove title attributes: general-template.php

// general-template.php
get_calendar()

What I'd like to change in this, in addition to the prev/next links handled in the attached patch, is the <th> title for day names. That should really be an <abbr> element wrapping the day name, rather than a title on the table heading cell. That would potentially have an impact on output, so probably should be discussed.

I left the title attributes on the day links with post titles, because that seems like valuable added information. Usual caveat, should be expressed in an accessible way, etc., but still needs to be provided.
