Each test scenario (i.e. luc, legacy app, tsm) has been split into a
separate file.

Setup steps which have to be performed for every scenario are moved into
test-general-setup.xml

Cross-references are used so that the test overview links to each test
case, and the "Testing" page links to the general setup and also each
test.

test-example has been removed because it is no longer necessary.

The improvements to the layout of the test document are that the
individual tests will now show up on the table of contents.

The Target Startup Monitor (TSM) tests check that the following cases
attempt to change the node state:
* The Node Startup Controller starting
* focussed.target starting
* unfocussed.target starting
* lazy.target starting

The following case should not attempt to change the node state:
* focussed.target stopping
