Citeproc style configuration
Add in config for choosing style guide to be used by Citeproc. There are 10 000 plus styles. Perhaps we should have 5-10 default styles for a Group Manager to choose from e.g. 'APA' and an option to search and fetch a style from Zotero API and 'install' via Configuration Manager.
