Disable autocorrect feature by default

[tdulcet]

• Due to the #4 and #64 issues, this temporary disables the Unicode autocorrection feature by default. 😢
• Added new option to reenable it for testing.
• Added Thunderbird specific workaround for not being able to access the subject and other fields in the compose window. See https://github.com/rugk/unicodify/issues/73#issuecomment-1154989856
• Incremented all versions to 0.5 for consistency with Thunderbird.
• Fixed issue with Unicode font conversion when selecting multiple lines or special characters.
• Added missing C, F, Q and q superscript characters that were included with Unicode 14 in 2021.
• Added new +, -, =, ( and ) superscript characters.
• Updated libraries.
• Miscellaneous other improvements.

I believe this should finally allow us release v1.0. The Unicode autocorrection feature could then be enabled in a future release, such as v2.0.

So needed some CSS adjustments: https://github.com/TinyWebEx/CommonCss/pull/2

looks good now with a proper warning message:

I also simply removed the confirm message for now. I mean, if one really skips the big yellow warning then so be it. It's not that bad. It does not kill the computer or have other non-reversible effects after all. They can just revert the setting and are fine. Also, it may be useful if you do not use one of the sites affected.

Also it was not really a great UI to have that default Firefox dialog somewhere in here, and worse, if you showed that popup multiple times, it tried to show a "do not disturb" checkbox, but the checkbox is not there… :sweat_smile: :sweat_smile:

Ha, it looks like you found a Firefox bug. I am able to reproduce it as well.

BTW, if you want to report that bug, feel free… :upside_down_face:
