node flags support

For running with --harmony, --harmony_proxies, etc. so we can write ES6 standalone executables.

According to https://github.com/thlorenz/v8-flags, this can't be set at runtime.

Think I'm just going to switch to using latest io.js stable, which should make this all a lot simpler and much more sane...

Ah... There is a gyp define for NODE_V8_OPTIONS we could set at build time which seems to do the trick:

npm install -g lone@0.4.2;
DEBUG=* GYP_DEFINES='node_v8_options="--harmony --harmony_proxies"' lone

Perhaps we should add lone.v8_options to package.json/config to make this easier?

That sounds like a good idea. Relying on command line invocation to compile is a little messy - trust me, I used to write Go code for a living :p
