Fixed a bug (NullPointerException) when attempting to save a configuration file in the following conditions:

• HackRF selected as output device
• HackDAC option enabled
• Selected mode is a baseband mode

Enables all Eurocrypt options on fsphil's build

• Added closed captioning (CEA/EIA-608, line 21) option to VBI Settings section.
• Added audio options when FL2000 device is selected as output.
• (Non-Windows systems only) The detected location of yt-dlp is now saved to preferences and will be recalled, rather than going through the detection process again. However, if yt-dlp is no longer in the saved location, this will trigger the detection process.
• Added the Java Runtime Environment version to the About box for information or troubleshooting purposes.

Refined the fix in the previous release to better support Java 22 and later.

Resolved an issue with path resolution on MacOS and Linux, where yt-dlp was not found when running the JAR file directly from the desktop environment and not from a terminal window.

Many thanks to dob205 on Discord for reporting the issue, and for helping me with replicating and identifying it.

Additions:
Added support for FlatLaf IntelliJ theme pack.
The Windows installer has been updated for this. For other platforms, see FlatLaf support in the wiki.

Fixes:
Fixed a bug which caused a NullPointerException when switching between themes using the arrow keys.

Fixes:

• Allowed files (preferably audio files) to be added to the playlist when a Philips test pattern is selected.
• Revised the warning message that is generated when attempting to add a Philips pattern to the playlist (which is not supported).
• Minor text revisions in the Philips test pattern settings dialogue ("time" rather than "clock").

Removals:

• Removed hacktv teletext demo page. If you need it, it's still available at https://github.com/fsphil/hacktv/blob/master/src/demo.tti.

Changes:

• The Download hacktv for Windows feature has been rewritten to accommodate Matt's fork. All three options are now available.
• The "Test signal settings" button has been moved to the Source tab. It is only visible when a supported fork is used.
• Added support for the --testsignals-path option, this is now used instead of changing the hacktv working directory.

A more sane rewrite of the timestamp bug fix. Also applies to streams using yt-dlp, which was left out in the previous release.

Almost a year to the day when I added workaround code to fix the timestamp bug in Captain Jack's fork (release 2024-02-22), I've finally found a solution to the problem. The timestamp should now render correctly.
