Add support for system-level settings

In addition to the traditional per-user settings, there is now also a
system-wide settings file affecting all users. The file's platform-
specific default location can be overridden at build time.
The qbs-config tool can write these settings via the new --system
option.

[ChangeLog] Introduced the concept of system-level qbs settings
