This leads to multiple problems
1. We cant assume only items with id='current' are stored in the node
which would lead to retracting 'current' but another item would become
the last published and sent to users
2. Even if we have a SingletonNode retracting the only item means the Node
would be empty and offline clients would not receive the last published item
on coming online, because there is no item anymore
Instead we always publish an empty item from now on
- Convert xs:boolean values in bookmark module
- Use python booleans for minimize and autojoin in other parts of Gajim
- Use add_bookmark() instead of manipulating the bookmarks dict
- If the server implements XEP-0398 we dont need to add the avatar sha
anymore, the server adds it for us.
- It also means we dont have to query our own avatar from vcard at start
because the server tells us the avatar sha that is published with the inital
presence reflection
- Use emoji data from a generated dict based on the offical unicode docs,
this makes it easier to update in the future
- Rewrite the emoji chooser
- Add a search field to the emoji chooser
- The emoji chooser is loaded async
- Update to current Unicode 11 Noto theme
Add method that sequentially works the steps we have to do
before sending first presence
- Move Delimiter into own module
- Move Metacontacts into own module
- Rework the MAM Preference dialog
- Move MAM Preference dialog into a new gtk module

- Add a misc module for smaller XEPs and move EME, Last Message Correction
Delay, OOB into it
