Update renamed-styles.json

Updates from https://github.com/citation-style-language/styles/blob/master/renamed-styles.json
Look for abbreviations for longest possible match first
Don't drop last word when abbreviating journal names
Use the longest abbreviation possible.
E.g. Fictional journal "Journal of Annunc Materials" (obviously annunc is not a real word)
Use "annunc-":"annunc." substitution instead of "annu-":"annu." resulting in "J. Annunc Mater." instead of "J. Annu. Mater."
Abbreviate plural forms of words same as singular
If abbreviation is same as key, it's still valid

Merge pull request #392 from aurimasv/abbreviations

Fix abbreviation algorithm
Update maxVersion
Abbreviate word pairs (e.g. New York -> N. Y.)
Update abbreviations.json

Remove overrides for titles we now abbreviate correctly, and don't
delete potential prepositions that are rarely used as such in journal
titles ("hyphen", "midst", "minus", "modulo", outside", "pace", "past",
"plus", "round", "save", "til", "till", "times", "vice", "worth")
Fix name on abbreviations list
