upgrade deps; closes #3018 (WIP--DO NOT MERGE)

[boneskull]

upgrades: production

• commander
• debug
• diff
• glob
• supports-color
• browserify (affects production)

upgrades: development

• karma-phantomjs-launcher
• karma
• karma-sauce-launcher

modules added

• buffer

modules removed

• lodash.create
• phantomjs (installed via karma-phantomjs-launcher instead)
• readable-stream
• json3 (this was for IE7/8's crap implementation)

[boneskull]

The story on buffer is that browserify@14.4.0 ships with buffer@5 which is incompatible with IE10 and older. So we have to explicitly depend on buffer@4 and tell browserify to use it.
