Add full Apache 2.0 licence notice to all relevant files

- mdcms.py: expand abbreviated notice to full boilerplate
- app/index.html: fix version in comment header (v0.3.8 → v0.4)
- app/config.yml: add missing final two lines of notice
- app/theme.yml: add full licence notice (was missing entirely)
