dev/core#2282 Use the proper content type for ICalendar link

[ahed-compucorp]

Overview

iCalendar (RFC 5545) is a standard method of transferring calendar information between computer systems and is used to import and synchronize events on various platforms and using the proper content type will Improve the end-user experience.

Before

CiviCRM will use the content type of text/plain for ICalendar feed.

After

CiviCRM will use the content type of text/calendar for ICalendar feed.

Technical Details

Because of CRM_Utils_ICalendar::send will check for content type of text/calendar and send a content disposition header with empty filename, I updated it to check for $filename instead.
