Showing the bootstrap state and showing there are unverified devices is
still missing.

Added support for refreshing the device list, marking current device with a checkmark instead of a lock

- Fixes scrolling to an event not being reliable
- Adds new /goto command that can open URLs, go to events, or go to message indexes.
- Refactored ChatPage::handleMatrixUri() to contain the handling originally in Nheko::openLink(), and makes it return a boolean based on whether the URL was handled internally or not.

- Now scrolls entire profile instead of only device list, improving the experience on smaller screens
- Fixed centering of room name
- Allow profile to be sized smaller to match the new scrolling behavior
- Silenced warning about room being null for global profiles
- Matrix URLs now open global profiles instead of room-specific profiles if the user is not in the currently opened room
- Opening global profile from room specific profile now uses openGlobalUserProfile function instead of reinventing the wheel

- Set a minimum width on the profile window (avatar size + margins)
- Made avatar editing a separate button, so you can zoom in on your own avatars
- Added hover text to avatar/displayname change buttons, which clarify where they will apply for global/room-specific profiles
- Added display of room name for room-specific profiles, with hover text that explains what that means.
- Added way to open global profile for users from their room-specific profiles (globe button next to room name)

fixes #461

As well as selecting more join rules.

We explicitly set a parent. We can't assign to
ApplicationWindow.transientParent though, only to
Window.transientParent, so we just call setTransientParent in C++.

RIP

Something is still wrong on shutdown, need to debug that.
And CI will fail.
