[amarok] src/context: Add analyzer applet to the user's existing config.

[Mark Kretschmann]

Git commit 7f7de7db91c6d544785f89613843dbc361195c76 by Mark Kretschmann.
Committed on 24/05/2013 at 19:56.
Pushed by markey into branch 'master'.

Add analyzer applet to the user's existing config.

This trickery is needed to give the new analyzer applet some
visibility when upgrading to Amarok 2.8. We rewrite the
config carefully so that the applet gets inserted in a sane position.
We also take care not to re-add this applet, in case the user
has explicitly removed it earlier.

Testing welcome to ensure that no special cases are ignored that
could screw up the config somehow.
