JsonWizard: Allow for more control of line layout in templates

Browse Source 
Expand "\n", "\\" and "\t" in the templates to a linebreak/single '\'
character/tab respectively. Also enable line continuation with a '\'
character followed by a line break.

This allows for nicer output from the templates, avoiding spurious
blank lines in places.
