First pass at Algoma U tpac skin for rel_2_7

This was done in a hurry and simply handles the esential links, logos and branding.

 *changed the main logo on the homepate
 *changed the header links to reflect new library website
 *added footer links
 *added config file based on lul's to enable OpenURL

In addition to adding the same graphical header so that the OPAC
more closely resembles the new Wishart website, this change
incorporates several smaller fixes:
    * replace the AlgomaU "small university/big education" logo
      with the small AlgomaU wordmark
    * center the logo via CSS, not <center>
    * fix vertical centering of the "your account log in" text --
      needs margins only left & right, not on all 4 sides
    * replace border on the user/pass input boxen so that they
      are visible once again.
