Also updated the README to reference the iCalcreator GitHub.

Issue [#2046935]: Added support for "long text" and "long text and summary" for the LOCATION and SUMMARY fields.

date_repeat_split_rrule() calls functions from other .inc files, but doesn't
directly load those files. So I made Date iCal load them before calling it.

Added a version number to help me determine which version of Date iCal is being used by something who's having problems.

Added the hook_date_ical_post_render() alter hook.

Issue [#2018285]: Optimized the method by which the feeds parser reads data from the incoming iCal feed.

This hook allows modules to fix broken timezone strings in the iCal feeds they import.

Also cleaned up the way that timezone strings are handled by the parser, especially under error conditions.

date_ical_format_text() was going way overboard on it's attempts
to make text iCal compliant. I got rid of all the escaping, and also
all the extra endlines which the drupal function was adding at 80-char
boundries.

I added the summary_field option to option_definition, which should
fix several (surprisingly unreported) errors related to Features and first-time
setup.

Added the view object as a parameter for theme_date_ical_icon, which gives
additional context for any module that would like to override that theme.

Issues [#1931020] and [#1935820]: Allow custom fields for summary. Fix repeating events causing duplicates. Add @file to DateIcalFeedsParser.inc

DateIcalIcalcreatorComponent::component is no longer protected. This allows hook_feeds_after_parse() implementations to alter it.
