Arduino-mk Makefile and project initialiser

This script can be used in its basic form create a project specific Makefile
for use with Arduino-mk. Addionally, it can be used to create a template
Arduino source file and a traditional boilerplate project file structure.

Example:
    * Run prompted within current working directory: `ardmk-init`
    * Create Arduino Uno Makefile (useful within a library example): `ardmk-init -qb uno`
    * Create boilerplate Arduino Uno project in current working directory of same
      name: `ardmk-init -b uno --quiet --project`
    * Create Arduino-mk nano Makefile in current working directory with template .ino:
    `ardmk-init -b nano -u atmega328 -qtn my-project`

See `armk-init --help` for CLI arguments
