v1.0.0

Whoa. It's like, ready? Just one minor bug has been reported in the last month, so now's as good a time as any to officially release this thing. A few small changes compared to the last RC:

• Drop the need for .default when using require('yaml')
• Fix for the bug part of #28, now always putting collection comments on their own line
• Fix setOrigRanges() for flow collections, adding origOffset to FlowChar objects (Fixes #40)
