Release 1.1.1

This is a pure bug fix release that removes three problems that were overlooked in the 1.1 release.

Bug fixes

• Version strings in framework_version are now coerced, so that for example 1.1 becomes 1.1.0 automatically.

• Lewis does no longer hang forever when starting a network service fails.

• Switching setups at runtime works again as in release 1.0.3, in 1.1. it had been disabled due to an oversight.
