Fixes issue where the ox-icalendar export uses an inconsistent mix of
dos and unix style line endings.
* lisp/ox-icalendar.el (org-icalendar-fold-string): No longer converts
to CRLF, instead delegating that to `org-icalendar--post-process-file'.
(org-icalendar--post-process-file): New function to handle exported
file post-processing. Converts EOL to CRLF, and then runs
`org-icalendar-after-save-hook'.
(org-icalendar-export-to-ics, org-icalendar-export-current-agenda,
org-icalendar--combine-files): Call `org-icalendar--post-process-file'
instead of running `org-icalendar-after-save-hook' directly.
* testing/lisp/test-ox-icalendar.el: New file for unit tests of
ox-icalendar. Add an initial test for CRLF line endings.
