Add a way to redirect the "install settings"

Browse Source 
If the default install settings contain a value for
"Settings/InstallSettings", then that is used as the actual path for the
actual install settings instead.

If the path is relative, it is interpreted as relative to Qt Creator's
applicationDirPath.
