Please bear with me, I'm a git noob and this is my first pull request.

The URL in the homebrew installation command was incomplete so I fixed it.

Also, angularjs-file-upload 0.1.4 could not be found, resulting in a build error, so updated to 1.1.8.  Full disclosure, with this change I got h0tb0x to build but get a runtime error:

Schema "h0tb0x" version is: 2
Running with config: 
  ApiPort: 8000

Not sure if this an issue with updating angularjs-file-upload, or if my father-in-laws' router isn't playing nice - still playing around, going to be off the grid for a couple days, so figured I would send a pull request.

Also, FYI - I hit the following installation issues on my Macbook, didn't include them in the readme:

* I had a really old version of XCode (v3.x.x), had to upgrade to v5 to get some of the homebrew packages to install.
* I needed to brew install mercurial to get h0tb0x to build.
