merge of SkiOSSampleApp into SampleApp, still a work in progress

Now that we have skia_os, we can merge the iOS sampleapp into SampleApp.gyp.  Here's a stab at it... the project is generated, but it generates plenty of errors when you try to build it.

I think we might as well commit this and then you can fix it up...

Here's how to generate the XCode project (must be run on a Mac):

cd trunk
make clean
GYP_DEFINES="skia_os=ios" ./gyp_skia
