Extension Updates for RL 2.0+: Signal State Machine and Deferred Command Queue

Not sure if this is the correct place to let everyone know, but I've forked the Signals-based state machine for RL1 and updated it for use with 2.0+.

I've now updated both Signal State Machine and Deferred Command Queue to be RL2.0+ compatible.

Signal State Machine

From a usage stand point, it should work exactly the same way as the old version (except for how it hooks into Robotlegs, a class implementing IExtension is included). The one exception to this is fallback commands. I wasn't clear on how they worked and couldn't find documentation explaining them. As I didn't have any need for them in the project I was working on, I didn't put a lot of effort into understanding them and dropped them.

I'm also yet to update the tests, but I plan to do this when time allows.

Deferred Command Queue

This one is completely updated including tests (which I ported to FlexUnit). It's not setup as a context extension.

    Thank you for sharing the rl2 state machine with us, David!
    I'll move the thread to Resources and Examples.

    No problem.

    I've also now updated Stray's DeferredCommandQueue utility to work on RL2.0+.


    Hopefully someone finds these useful :)
