Disable Nginx 404 handler for static assets

This extra production-minded rule prevents some useful plugins from working
properly, such as Dependency Minification and Media Placeholders, since
they rely on the WordPress handling requests to JS, CSS, and images.

Disable Nginx 404 handler for static assets
Move xdebug controls to executable files

This makes the files accessible to use outside of an interactive shell environment.
Rename default config to always come first

If a custom config file is added that starts with a number or A-C, it will be the first server defined in Nginx. That means the ip address by itself will not point to the default server, but rather whatever server is defined first.

Merge pull request #122 from johnpbloch/move-xdebug-on-off

Move xdebug controls to executable files
Remove poor implementation of Watchr

Having a watchr script was great in concept, but not entirely necessary. Now that we've improved our provisioning time for existing setups, typing `vagrant provision` at the command line initiates a process that only takes 11 or 12 seconds. Automated restarting of services on config file changes is no longer really necessary.

If we do introduce this or something like it in the future, we need to make sure it falls in the 'very useful' category.
