CML boolean type compiles into #define and #undefs. This is not useful for capabilities since a value of 0 or 1 can be used automatically for setting or unsetting bits in permission words. Meanwhile using an integer type with 0 - 1 range has a worse usability experience than the boolean Y, N. Also moved parsing of container.template.cml to newer Python argument parsing format.
