Bunch of new stuff in 5.5.14, I also had to disable the varnish extension as I
couldn't get it working locally. Starting to think that perhaps I should build
out a Linux VM to run the updates against as doing so on OS X has been a bit of
a pain with a handful of packages.
Added some logic to strip out the null character APC stuff, added some more extensions and added some logic to attempt to install via `brew` when the argument "brew" is passed to the update script
