line wrapping, updated PHP and zsh, added Python in .sublime-settings file

I rewrapped all the comments in the .sublime-settings file to ~80 chars/line so it can more easily be read in narrower windows (some of the settings lines are still longer, though). Next, I added a little bit more zsh support (added zsh as a "binary" and in the "file_name" regex with .bash and .sh) and added a small Python section - filenames .py|pyw|py3, and binary python. Finally, I remember when I was learning PHP 15 or 20 years back that some file names had the version number appended, so I changed the "file_name" rule to not only match .php, but also .php(3|4|5). That may not be common anymore, but legacy stuff hangs around forever!

I did exactly the same things on the master branch, I'll be sending a pull request for that momentarily...
