AngularJS with Web Speech API integration

AngularJS TodoMVC with Web Speech API integration. Initial commit - not completely cleaned, and no unit tests included. Since this project extends base functionality of TodoMVC, I have no expectation of permanent addition. stephenplusplus expressed interest in viewing this project.

Note:
Web Speech API is finicky transcribing numbers. Sometimes returns digits, sometimes returns word.

Known issue:
Speaking 'Delete X' or 'Complete X' on a filtered list removed at the unfiltered index :)
