Align Capstanfile syntax to Docker file #106

Although Capstan and Docker differ in some aspect, they do share common functionality:

Both use a base image to build a new one (FROM vs base)
Both execute commends on image build time (ADD vs files)
Both execute command on image init (CMD vs cmdline)

For users who are already familiar with Capstan file, having Capstan support a subset of Docker syntax will be useful

Also there is a convention to write Dockerfile commands in upper case letters. But all Capstanfile examples I saw using lowercase commands. Having commands in uppercase makes it easier to visually separate commands from their arguments.
