Inform people how to get homebrew-php

When I followed the brew installation instructions, I received the error:

"php-cs-fixer: Missing PHP53, PHP54 or PHP55 from homebrew-php. Please install one of them before continuing"

But, there was no info on how to get that. Adding a section to the README, though ideally this error message would contain it. (I wasn't able to find this string in the source, though.)

Updated the url in the download instructions

This is a fix for #334

as I did the change through the github interface, I haven't regenerated the readme itself. Tell me if it is OK

Fix $open_mode value from constant to string

This was a bug in documentation which I fixed. It worked because `r` (if not defined) was assumed to be `'r'` (string) + E_NOTICE.
