Updated MARC Templates

MVLC has updated our MARC templates quite a bit over the past year. Highlights since our previous updates include:

• More RDA fields in most templates.
• Add copyright symbol to 264$c where 2nd indicator is 4 in book (ABK) and large print (ABKLP) templates.
• Add a video game template (VIDEOGAME). 

If you're interested, you can grab these templates for your own Evergreen installation via git. The branch is shared here and here. Everything is in the top commit on the branch, so if you're not running master, you can just cherry-pick the branch into yours. (You are installing from git, aren't you?)
