Atomizer 2.0.0-alpha.1

First alpha release of 2.0 includes:

• General configuration is no longer passed in the config property of the config object. Instead, the values previously found within that object are now considered "options".
• defaults options/config was not being used, and has been removed from examples. We'll see if it makes a comeback at some point.
• CLI no longer requires a config file to be passed
• RTL processing now triggered via a bool option called rtl. start and end options have been removed in favor of rtl.

Still to come in future alpha releases:

• Better CLI support for options (namespace, breakPoints, etc)
• Enhanced breakpoint support
• Pseudo-class support
• Contextual selector support?
