Adding demo data & a few minor bug fixes in the default template.

This is my first run at creating some demo data (Org, branch, office, warehouse, staff & vols). I plan to remove the regression data which was a very early and crude set, hence the changes to all the various tasks,cfg files.
When running the smoke tests on the default template a few bugs were uncovered which I have fixed.
Made a fix to role tests prompted by ticket 1405, whilst the test now runs it looks like a number of the tests fail so maybe Michael needs to look at this.
