Redid Primitives

I'm working on fixing some of the other bugs so that I can test. Also
created a file that will load and run the test cases. It's called
runall.ss

P.S. Sorry about earlier. :)
Forgot these files. No real changes except

for that in order to get env.ss and interpreter.ss to load I had to
merge them into one file.
Merge branch 'master' of https://github.com/lelisadav/20131430

Conflicts:
	parse.ss
