* add get-mime-original apis
* remove unused control
* add 'Show full message' buttons
* split reusable WebViewActivity from LocalHelpActivity
* add FullMsgActivity
* load html via AsyncTask
* adapt to changed api
* handle mailto:-links in WebView
* block loading remote images by default, add user setting always/once/never
* do not hide 'Once' button in always-mode, playing around a day with hidden 'Once' that looks more like a bug :)
* wording: as 'Always' affects all messages, it is better to speak of multiple senders
* wording: use 'Load remote images'
this makes it easier for the user to find the option
if one sees, images are missing in the document.
* wording: shorten text.
* wording: change 'may' to 'can'. 'may' sounds a bit as if someone allows this.
* Don't use AsyncTask
* check 'once' if appropriate
* use lite-colored checkbox-emoji in dark-theme
* add comment about missing error logging
