Computed Property Re-Write.

[amiller-gh]

I'll add the /dist directory to the gitignore file after this commit. Only things in /packages and /test are applicable.

• Complete re-write of how computed properties work
• 81 Computed Property tests added
• QUnit now runs in command line
• Upgrade to HTMLBars with a stable hooks format (with re-write of some hooks)
• LazyValues now work as value streams and have a .set property to push changes to the original context
• Cleaned up code

If you wanted to remove the dist folder for this commit to make this PR a bit more reviewable, you could update your gitignore locally, then run:

# recursively remove all files from the git cache
git rm -r --cached .
# add em back
git add .

1 sec, I'll fix it. I think that will still show all the files removed in the diff, it won't be much more legible. I'll reset the dist file to what is currently checked into master and push without compiling them again

Ah, right, good point. Maybe using 2 commits here would be a good idea: the first could remove the dist directory from the repository, and the second to add the relevant changes.

There ya go :)
