the single quote / apostrophe character has no special meaning - only the double quote does.

the single quote / apostrophe character has no special meaning - only the double quote does (i searched RFC 2426 and 2445). the original vCalendar spec also gives no special meaning to the DQUOTE, but i haven't noticed this causing an issue (it's also not an ambiguous character like the single quote / aposthrophe) - i'm converting VERSION:1.0 entries into VERSION:2.0.
