Bug 12405 - Search links on callnumber fails on intranet results page

On intranet results page, the callnumber of items is a search like :
/cgi-bin/koha/catalogue/search.pl?idx=callnum&amp;q=[% result.itemcallnumber |url %]

The callnumber should be URI-escaped to avoid special URI characters like & , ? ...
If the callnumber contains some CCL words or parenthesis, the search will fail, it should be wrapped with double-quotes.

This patch adds this to catalogue/results.pl and catalogue/shelves.pl :
- uri TT filter instead of url
- adds double-quotes using there URI code %22 since its in a HTML attribute using double-quotes

Test plan :
- Edit an item callnumber with : & ABC 123
- Index zebraqueue
- Perform a search returning this item
- Click on the callnumber
=> Without this patch you get no result, because URL parameters are : idx=callnum&q=& ABC 123
=> With this patch you get results
- Set syspref QueryWeightFields off (because this is no bug if on)
- Edit an item callnumber with : AB(C) AND OR
- Index zebraqueue
- Perform a search returning this item
- Click on the callnumber
=> Without this patch you get no result, because the search contains CCL words "OR" and "AND"
=> With this patch you get results
