Bug 28802: Untranslatable strings in browser.js

Bug 28802: Untranslatable strings in browser.js

File koha-tmpl/intranet-tmpl/js/browser.js is not parsed by translation
process, which uses koha-tmpl/intranet-tmpl/prog/js/**/*.js
We must move it to prog/js.

Test plan :
1) Perform a search on staff interface
2) Click on a result
3) Check you see records browser
