Fix import of calendar events from The Events Calendar to Outlook.
The Events Calendar allows for the import of calendar events via download of a generated iCalendar file. This generated file contains the
X-WR-CALNAME header, which is a valid header.
Unfortunately Outlook chokes and will create a new calendar when it sees this header instead of adding the event(s) to the default Outlook calendar. This plugin removes that header from the generated iCalendar file.
