Allow Dockerfile as language / handler

This allows the FaaS CLI to handle your non-templated Docker builds.

See example of ImageMagick in the samples.yml file.

• Allow Dockerfile as language / handler
• Update Golang to 1.8.3 3f97a37
• Added -delete as an action to remove deployed functions

Support Ruby + CSharp templates

Templates can now be created for Ruby or CSharp .NET Standard 2.0 functions also.

Restores downloading of templates via Github

• Downloads templates from Github when missing from current directory. (removed between 0.4 and 0.4.5

Fixes for CLI

• skipBuild now skip_build in YAML
• sample (names) updated to be compatible with K8s naming
• quiet output for templating
• --squash flag available for experimental Docker daemons

Templates:

• made NPM quiet
• used curl instead of ADD https:// for watchdog - speed boost during templating due to caching
• templates now copy your handler recursively into target container
