Enables sending HTML emails and "resume from crash"

[boredsquirrel]

Description

removing unneeded lines and changing some settings:

• allow sending mails only when HTML-specific things are actually done
• remove anything regarding "debloat" (Thunderbird news are not bloat...)
• ~enable accessibility (this can still be disabled but it is important for usability)~
• resume from crash
• show condensed address only when in addressbook (this is no spam risk, and TB has GUI configs for that)
• collect addresses of people you write. Mail is not anonymous and stores data, this will make spam detection easier etc
• display inline images etc, this is very limited with sanitized HTML
• allow extracting calendar events, this is by choice via a popup
• enable the new tab page, makes no sense in TB

Reason and / or context

keep it minimal, dont force unnecessary things on users, making updating complicated

How has this been tested ?

Thunderbird Flatpak

this also affects this wiki entry

https://github.com/HorlogeSkynet/thunderbird-user.js/wiki/4.1.1-Calendar

when merged, the "extract calendar event" doesnt have to be mentioned, if it is removed, then it should.

I used TB without any hardening for a while and trust me, this feature is very fine.

accessibility actually seems to be about strange antivirus tools, I will disable it again

@HorlogeSkynet If the calendar event extraction stuff would not be disabled in the config, then the wiki entry would not be needed anymore.

I read the wiki page again and can't find any reference to "event extraction" feature (sorry if I didn't get you again)
