Updates script to fetch schema

Needed to add the 1.04 option and to alter the branch that gets checked
as they have been renamed at source
These changes enable the application to use the 1.04 schema

Sets the 1.04 schema as an option in the drop down menu and as the
default schema to test against.
This may not be the most desirable position, but it is consistent with
the way the application currently works.
Adds a test to check some basic validation against 1.04

Uses the new location elements to check that it fails proir to 1.04
and that it passes at 1.04
Made a change to the default settings file when testing locally.
