Adding proper argument parsing and building methods.

[jarulsamy]

Hey James,

I changed a few things,

• Changed to cmake for easier building.
• Added the necessary headers from other repos to avoid linking against other projects.
• Added proper argument parsing. combo.dict and featex.raw are now command line parameters that can be moved anywhere. This will make developing phoneclearly much easier.
• Prompts are now also command line parameters, supplied as quoted strings.

Things to note: I revamped the entire command parsing system. So playing the sounds is a little different. Please refer to the readme and test accordingly. If anything is not functioning properly please let me know. Although, I think this is production ready for phoneclearly.
