This release has a much better mobile view system without UserAgent detection.
It is based on the window width < 1000px and switching between modes doesn't need to reload the whole website (as RainLoop does).
Another benefit is a good view of the admin area on small screens.
1000px is chosen due to the Apple iPhone 12 Max being 926px in landscape mode.
Secondly i've dropped a few kb's of CSS and JavaScript, and cleaned up HTML files for yet another improved and faster response.
Also the messagelist now uses flexbox for easier items parsing.
Bugfixes:
- rename JavaScript "File" object to "FileInfo" to prevent conflict with native JS
- incorrect image glyph for disabled images in message
- mailbox search pagination failed
