[CoolTerm-Betas] CoolTerm v1.9.1b1 ready for testing

[Roger Meier]

Hello Testers,

v1.9.1b1 is ready for testing. Here’s what’s new:

- Implemented workaround for localization bug that causes an InvalidArgumentException when calling DateTime.now on some Windows 10 systems.
- Fixed bug that omitted the serial port selection and window position when saving settings.
- Added Find menu item to find text in plain text view.
- Fixed bug that would not properly save multiple macros to connection settings files on Windows systems.

Happy testing!

Roger
