Citation Styles

[jarrod-dalton]

We should maybe throw in a few of the most commonly-used citation style files (.csl), available at https://www.zotero.org/styles, in the templates folder. Perhaps with a way to change both the default .csl file (we have that already - just throw the file in the template folder) and change a specific project's .csl file from the console (maybe in edit_project()?)
