Remove tcp_nodelay directive

The reasoning here - https://github.com/h5bp/server-configs-nginx/issues/28 - seems to make sense. When we set `tcp_nodelay` to off, we tell Nginx to use Nagle's algorithm to figure out how packets should be buffered with a possible 500ms latency if it can't figure things out in time. This 500ms latency is something that even Nagle says (http://developers.slashdot.org/comments.pl?sid=174457&threshold=1&commentsort=0&mode=thread&cid=14515105) should stay in the 1980s.

Suggesting we remove this directive and leave it to Nginx's default `on` to *not* use Nagle's algorithm.
Process subdomains for each default domain we provide Nginx configs for.

This makes it easier to setup multisite with subdomains while avoiding too many file edits in the VVV base. Other modifications will still be required, such as setting up recognition for the new hosts on the local machine and in the guest, but this takes away the need to restart Nginx.
Check symlinked VVV site setup directories for vvv-hosts files

This allows directories in `www/` to be symlinked and still be picked up during `vagrant up` for use with vagrant-hostsupdater.
Fix typo
Update contributors list
Fix a small number of tabs -> spaces

Not entirely sure how we got stuck with spaces rather than tabs, or if that's even a bad thing. There were a few lines that had tabs that needed to be fixed.

Trim php.ini down to contain the most important info.

This should make it easier to find settings that need to be changed rather than having to skim through a bunch of stuff looking for something relevant
Add a documentation notice to the top of php.ini
update phpmyadmin to 4.1.2
Fixed typo in Grunt installation.
Added zip to apt_package_check_list.
Revert "Check symlinked VVV site setup directories for vvv-hosts files"

This reverts commit 6bd6419a669f5838f8eeb427cedf3e2e427dd7f1.

Symlinks may work inside the Vagrantfile, but the VM is not able to access them internally, so they do us no good.
