Modify grammer for loops, breaks, and continues
Implement intermediate transformations for new statement types.
Implement type checking for break and continue statements. (Surprise! There is none!)
Implement code generation for break and continue.
Add some testcases for for loops with break and continue.
A workaround that might fix continue not infinite-looping on for loops.
Add a regular while loop that should work without advanced features.
Merge branch 'master' into loop-stuff

Conflicts:
	lib/intermediate/program.rb
Fix bugs I overlooked. Regular while works again!
Fix ContinueLabelHelper
Add continue for all example
Fix continue so it doesn't, you know, crash my session.
Add some more examples. All of these work, implying break and continue are golden.
Add until test (with continue).
Fix some typos with until. Alas, it still doensn't work because negation isn't implemented yet :(
