Fixed parseFloat and global issues
Adding jshintrc to root, whoops

This should have been in the original jshint PR. It defines the correct
globals so jshint doesn't yell at us when using THREE for example
Squashed sizeStart and sizeEnd, and opacityStart, opacityMiddle, opacityEnd into size and opacity attributes respectively.
Trying (and failing) to get mat3 attributes working.
Moved angle and angleAlignVelocity to a shared vec2 attribute named angle
Added sizeMiddle functionality
Updated dev build
Bumped to 0.7.1. Updated README.
Made new SPE object. Updated README and package.json
Added new options; this is to unify the available options so most of the options have *Start, *StartSpread, *Middle, *MiddleSpread, *End, *EndSpread.
Started to implement the new options.
