This patch adds musical inscripts to OPAC's detail page
To test:
1. run previous patch test plan
2. apply this patch
3. edit a the marc structure of a MARC bibliographic framework, and in tag 031 enable the following subfiels to be visible in editor: 2, g, n, o, p, u
4. search the catalog for a record that belongs to that framework, and edit tag 031 with the following:
* 2:pe
* g:G-2
* n:xFCGD
* o:3/8
* p:'6B/{8B+(6B''E'B})({AFD})/{6.E3G},8B-/({6'EGF})({FAG})({GEB})/4F6-
* u:http://nonexistent.org/url/of/a/midi
5. save and click in opac view
CHECK => even though you add a 031 tag there is no musical inscript shown in opac view
6. in admin module enable OPACShowMusicalInscripts preference
7. refresh opac view
SUCCESS => it takes a few seconds to load, but you see a link that says 'Audio file' pointing to the URL you placed in 'u' subfield, and below you see the musical inscript
8. in admin module enable OPACPlayMusicalInscripts preference
9. refresh opac view
SUCCESS => You see a play button below the musical inscript, and when you click, the song is played
