Bug 29075: 'OPAC info' removed in branches.pl

In Administration › Libraries, we see content of OPAC info as escaped HTML.
This content may be long and seeing HTML tags is strange.

We should not show it in this table.
Or maybe create a modal preview of it (not escaped HTML).

To test :
1) Home > Administration > Libraries
2) In 'Address' column notice the 'OPAC info' field (if this one is
filled) with visible HTML tags
3) Apply patch
4) Repeat 1) and 'OPAC info' field should be gone
