Adding more tutorial files. Not fully working yet!
Ignore a few more local files
toolbar class was different from what was declared in CSS

A few changes around defining databases
Differentiatre between 'widgets' and 'tabs' in configure file. Later are always considered top level
Add default 'configure_base_layer' which creates a 'svg:g'

Added ws_url -  not sure anymore why :(
