v3.20

Added

• re.findall filter to extract, delete or replace non-overlapping text using Python re.findall.

Changed

• --test-reporter now allows testing of reporters that are not enabled; if a reporter is not enabled, a warning
  will be issued. This simplifies testing.
• email reporter (both SMTP and sendmail) supports sending to multiple "to" addresses.

Fixed

• Reports from jobs with monospace: true were not being rendered correctly in Gmail.
