Bug 2774 - Path to theme is hard-coded in many places

hard-coded. Now that interface and theme template variables are
available everywhere these paths should be corrected to use them.

- 'Locked' icon on fund planning page
- Tag and subfield edit icons on the authority, biblio editor, and batch
  item modification pages (Clone tag, delete tag, clone subfield,
  delete subfield, move subfield)
- 'Loading' icon when importing frameworks

Audio file paths corrected:

- Sounds for circulation.pl and returns.pl

Paths to DataTables assets corrected on:

- Transfers to receive report
- Holds queue report
- Holds awaiting pickup report

- Patron circulation history
- Update child to adult patron page
- Process offline circulations
- Catalog by item type report
- Serials statistics wizard
- Serial claims page
- Koha news
- Notices
- Batch patron modifications

Path to progress bar assets corrected on:

- Progressbar include file
- Stage MARC imports
- Manage MARC imports
- Local cover image upload

Other image paths:

- "Approved" checkmark image on tags review page
