Looking glass: Usability improvements

- Centered window
- Don't keep window above other windows
- Remove unnecessary about dialog
- Call Melange "Looking Glass" (it makes no sense for users to
distinguish between the two), and that's what the tool is called
in the keybindings and in the panel troubleshooting menu
- Have the logs shown by default (that's why most users want to see)
