Calabash ios server

Hey Karl,

Here's the pull request that adds symbiote support to calabash 0.9.x.

On the menu:
- added a git submodule for symbiote, pointing to the latest commit that actually works
- added relevant rest resources (dump, orientation and static content)
- added flash method on UIView

As far as I can tell (tested on my production app):
- the basics work: symbiote loads the tree and highlights the elements in the "screenshot"
- iPhone 4" is supported. It's a little whacky, the boxes are off, but I think that's a symbiote problem (the css seems to be on the older aspect ratio)
- flashing works just fine
- "highlight" doesn't but, then again, I never understood what highlight did, so I can't really tell :)
- "touch" doesn't, because it's wired to the Frank touch category that doesn't exist in Calabash. Getting this to work means getting the touch playback thing implemented in symbiote. I lost my JS skills when I quit the ActionScript world, so I didn't push it that far.

For licensing, as mentioned in my last email: my code is WTFPL, the rest is Pete's code, so probably Apache.

Let me know if that works for you or if I should rework anything.
