Pkg.GitHub: generating HTTP verb commands was dangerously broken.

Fortunately, nothing bad happened here, but this ended up turning
everything into a DELETE request. Yikes. It also turns out that not
only does doing a GET request with `-X GET` not work in curl, but
doing a HEAD request with `-X HEAD` doesn't either.

Pkg.submit(pkg,[commit]): auto-submit PRs to GitHub-hosted packages.

It's downright magical that this works. Currently this only opens the
URL to create a pull request automatically for you on OS X since the
`open` command does the right thing there. Is there a way to open a
URL on other systems? Windows, Linux?

Fix \ and / for diagonal matrices
Re-apply @stevengj's commit e956b3c36f5fea929d5af8cd17b64682f7.

GitHub won't let me download or recover this commit, even though it's
very much publically visible:

https://github.com/JuliaLang/julia/commit/e956b3c36f5fea929d5af8cd17b64682f7

The easiest way to recover from the accidental forced push of master
seems to be to just re-apply this lost commit and carry on. See
