More profile improvements:

- 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
