Sorry, no fun for you!

fixes #632

- 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)

- add missing mimetype
- allow removal of images from pack
- allow GIF as a format
- don't divide size by 2 if the image is very small already
