- Move out all shortcuts from their central file to the component they
actually belong to
- Get rid of DebugConsoleLoader and the multiple consoles handling mess,
have only one global console
Replace broken old utils.debug(...) (since the utils.js → Utils.qml
transition) with a declarative approach:
a console can now be opened with by placing a `DebugConsoleLoader {}`
anywhere.
mainUI has a default console opened by F1/alt-shit-c when no other
console is loaded.
