blade tutorial1 still working
blade: now using isArray-polyfill for simpler interop

Since leaflet now uses Object.prototype.isString to check
that objects are arrays (instead of the earlier instanceof
Array methods), interop can be made much simpler by simply
using the new isArray.js polyfill.

blade initialization now does very little patching -
vector types advertise themselves as isArray.js producers
and the polyfill ensures that leaflet can consume these
container objects.
release: strokes-0.3.1
version bump to 0.3.2-SNAPSHOT

Also updated README to 0.3.1 and added information about mrhyde.
