Message:

* shoes/world.c: introduced the new shoes_world_t struct so I can start to implement multiple windows soon.
* shoes/app.c: the shoes_app struct is now wrapped by the App class.
* shoes/ruby.c: heavy reorganization of how blocks are called. prevalent use of instance_eval has been abandoned in favor of evaluation at the app-level and tracking of canvas nesting. i just think instance_eval was too confusing for beginners, I'm much happier with this. In this way, instance variables can be used to store elements rather than plain variables.
* samples/: use of instance variables to store controls and changes to reflect the new scoping. this revision breaks a lot of old code and doesn't yet compile on osx and win32.
