Comment 1 for bug 1795469

I just created a branch for this called user/sandbergja/lp1795469_add_cn_suffix_to_opac_holdings_order

Here is a link: http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/sandbergja/lp1795469_add_cn_suffix_to_opac_holdings_order

And here are the testing notes from the commit message:

To test:
1) Create a bunch of Call Number suffixes in Administration -> Server Administration -> Call Number Suffixes.
2) Go to a bib record, and add a bunch of holdings, all with the same call number label, owning/circ libraries, item numbers, and parts (if using parts) but with different barcodes and CN suffixes.
3) Look at the OPAC view of these holdings. Note that they are in order by barcode, without any consideration for the CN suffix.
4) Apply this commit.
5) Look at the OPAC view again. Note that they are now sorted by CN suffix, and then by barcode.
