 Bug 14306: Changes for basket and detail templates

A simple regex is added to the basket and detail templates to select the
URLs passed separately from MARC21 555$u by GetMarcNotes. Note that the
regex tests if a note starts with http:// or https:// and does not contain
any whitespace in order to be considered as a url.
These URLs are put in an anchor tag.

This touches four places:
[1] opac detail, tab title notes
[2] catalogue detail, tab Descriptions
[3] opac basket, more details, notes
[4] staff basket, more details, notes

Test plan:
[1] Edit a record. Add a 500$a, 555$a and a URL in 555$u.
    Put "http://this is not a url" in the 500$a (whitespace!).
[2] Check opac-detail, tab Title Notes. Check the URL.
[3] Do the same for catalogue/detail.
[4] Add record to cart in OPAC. Open basket. Check More details.
[5] Repeat previous step in staff.
