Remove the camel-case checker.

It produces way too many false positives on our own headers to be useful.
Single quotes are enough here.
Add missing header include guards.
Normalize signal/slot connections.
Use const references in foreach where possible.
Remove duplicate include.
Normalize new lines at file endings.
Use the dummy detector on QNX until we have something better there.
Silence a few compiler warnings.
Add missing license header.
Also add license headers to QML files.
Don't hardcode my name/email for the CMakeLists.txt license either.
Use recursive filter models in the QtQuick2 inspector.
