Fixes to validate better with CastFeedValidator

Previous releases didn't send the correct Last-Modified date or Content-Length headers.

Bug Fix release

Fix other blocker bugs introduced during refactor.

Now properly works with PHP8, and doesn't crash complaining about $argv or CLI_ONLY.

Bugfix release

This releases fixes a small but important bug in the previous release which prevented it from working in a web server context

Updates and bug fixes and a comprehensive test suite!

Changes since the last published release:

1.25 2021-02-26

            Prevent scanning of files which are still being uploaded, and
            add min-file-age option to adjust this

1.24 2021-02-26 Add a comprehensive unit test suite!

            A bunch of changes designed for better code re-use, such as not 
             using defines inside classes, and allowing programmatic
             overriding of properties of RSS items.

            Fixes to the generation of the media base URL.

            Better handling of image URLs.

            Don't save images from media files if one already exists but it's
             of a different type than the one in the media file.

            Fix a bug when DESCRIPTION_SOURCE is summary and summary is the default
              (which is the description).

            Allow generation of empty podcasts on the CLI (mostly for testing)

            Upgrades to getID3 to fix a few other bugs I encountered during testing.

1.23 2020-02-23

            Use the filename of a media file as the default title instead
            of (untitled). Suggestion by wesyah234

1.22 2020-01-19

             iTunes categories now use comma instead of pipe as a separator.                
            Characters which are valid UTF-8 but invalid XML are removed.
            Most ini examples updated to use double quotes.

1.21 2020-01-10

            Uncache the podcast when the configuration changes, making it
            quicker and easier to experiment with settings.

1.20 2019-12-30

            Cache files per media-file, which speeds up large podcasts
            Upgrade bundled getID3 with better MP4 support
            Support for <itunes:explicit> tag
            General speed improvements

Automatic cover art now also works for MP4 and M4A files

v1.19.1

Whoops - be more defensive for files WITHOUT cover art

Use episode images embedded in media files (and other bug fixes)

• automatically extract cover art from files as episode images
• fix image URLs (!)
• fix a long standing URL detection bug
• better command line options (mostly for testing, but could be useful if you want to create your feeds in advance)

Fixes for PHP7

This version should work correctly on newer versions of PHP.

v1.11

Changes since last release:

• Upgraded getID3 (so better tag detection)
• Supports M4A podcasts as well
• Works properly with PHP7
