fix#1836
AvatarSelector is mostly copied from AttachmentTypeSelector. I first started to make it a subclass, but there were so many functions that had to be changed that I decided against it (esp. also the constructor, so I would have had to create another constructor to allow AvatarSelector to bypass the "normal" constructor). Could still be done though, of course.
I think (hope joy) that the commits are clear enough that this can be reviewed commit-by-commit. In the first commit, commenting out code means "Moved somewhere else"
I found it easier to look at the first commit using gitk than GitHub as GitHub doesn't show it as copied from AttachmentTypeSelector but as a new file. (of course you can also just review normally, going throug it file-by-file :)
* Don't show remove button if there is no image yet
* Remove unnecessary animation that just made things look worse
* Delete now-unused ClearProfileAvatarActivity
* For groups, also use the attachment-chooser-dialog
* Remove confirmation dialog for removing avatar (The user has to confirm anyway, and this was not correctly translated)
* 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

Using both `setMessage()` and `setView()` on the same AlertDialog,
on small screens the "OK" and "Cancel" buttons were not be show. So, put the
message into our custom view.
