Allow apostrophes in names

Apostrophes can be used as "single-quote" string delimiters in many programming languages. They can also have special meanings like indicating the beginning of an in-line comment in the code. Because of this, Riot would need to escape and unescape the apostrophes depending on where the name is being passed/stored/displayed. Escaped character codes are longer than their unescaped equivalent, so the maximum length of the name strings could also increase in the database, which might be incompatible with existing code. It's probably not worth the hassle and risk of allowing apostrophes breaking things or even introducing data security issues.
