moving codemirror to submodule
* all submodules being moved under "deps"
* lib folder removed
* building this project requires the presence of the deps folder and of git submodules being initiated, "rake build-deps" (not done yet) will move all necessary files into their proper positions
* i like puppies
rake task for dependency building
* rake task build_deps to build dependencies into public/lib
* added gitignore entry to ignore built files
assets submodule and a little experimentation
* assets submodule now in deps, will be added to build_deps when there are actually assets to commit
* expirimenting with resizing and otherwise modifying the codemirror
* oh git submodule, how did i live without you
