Include Call Number Suffix when sorting copies in the public catalog

[Jane Sandberg]

Currently, the copies displayed in the public catalog view are sorted by the following fields:
* Org unit name
* Call number sortkey
* Part sortkey
* Copy number
* Copy barcode

This leaves out call number suffixes. We use call number suffixes for volume numbers (e.g. V.1, V.2), so it seems very natural to include those in the sort as well, maybe between call number sortkey and part sortkey.

This commit seems like a very good model for accomplishing this: https://github.com/evergreen-library-system/Evergreen/commit/ef697352585e0f7fff258e4fbec1dec03cf839ce

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.

This worked for me, remember to restart apache when testing to apply the change on a running system, took me a few minutes to remember that.
