Standardize on em dashes

[JanelleJenstad]

We have been inconsistent in our use of em dashes and double hyphens. @martindholmes and I noted that "There are 89 instances of double-hyphens in the TEI source files, some of which look like they would have to be retained (because they're part of some formal system such as a keyword taxonomy, or they're exemplifying how to create a comment), but most of which could be changed to em dashes. There are 317 instances of actual em dashes, so they are the majority."

With @martindholmes walking me through the process, I made three edits on the dev branch. I will continue this work in my own branch and update the style guide.

[sydb]

Not sure I see a need to be using a separate branch, here (except for practice).

[JanelleJenstad]

I'm making a branch only because I need the practice.

I'm resuming @JanelleJenstad and @martindholmes's work on this ticket with @sydb's guidance. I have saved the changes directly to dev.

I have saved changes from double hyphens to em dashes to the following files within Source/Specs/*xml:

  There were also some date ranges that had double hyphens instead of en dashes, so I have updated those instances accordingly within this ticket also (if there are objections, let me know and I can revert):

• [ ] locusGrp.xml

  <locus from="37" to="58">37--58</locus>
  <locus from="82" to="96">82--96</locus>

Also, I changed double hyphens to em dashes in the following files within Source/Guidelines/en/*.xml:
