Change which files are content to make building project easier.

[grilledham]

• Database files no longer required content, they are build on startup.
• Removed appsettings.Development as it wasn't used.
• Rename appsettings.json.template to appsettings.template.json
• If appsettings is missing create from template as pre build step.
• Prevent package.json + package.json.lock being copied to output.
