As a counterpart to `deploy:setup`

Fixes #6
So *maybe* a good idea to prompt beforehand
Simplified varnish cookie cleanup rules

* Removed cleanup of 'has_js' (remnant of drupal stuff from vcl template)
* Removed specific cookie checks, instead removing any underscore prefixed
* Left in removal of Google Analytics "utm" prefixed cookies (debateable, @ericclemmons might have opinion here)

Fixes #28 but more vcl cleanup to do...
Simplified cookie logic in receive/wordpress.vcl

* The existing wp cookie check was *starting with* `wp-` or `wprdpress_`, but would not match a 2nd or higher position wp cookie
* The second url check for `wp-(login|admin)` was no longer necessary, so removing all cookies past that point is more efficient
Removed extra GA cookie checks (turned out to be components of __utmz, not cookies themselves)
Switch varnish from malloc to file caching backend

Fixes #53
Documented genesis:teardown
Removed cache bypass for local.* hostname
Added unattended install of postfix. Fixes #37

Could potentially add two things here:

* template for /etc/aliases, where user can define an off-server email to which any system emails should be sent
* template for /etc/postfix/main.cf, with optional support to relay to external smtp server (eg: gmail)
Added mail.postmaster var and /etc/aliases template

See http://www.feep.net/sendmail/tutorial/intro/aliases.html
Remove caching for static files
Fixed typo in PHP ini for date.timezone (missing closing quote)
Pipe all requests for wp-login or wp-admin

This appears necessary for the web ui installs/updates to work. Should fix #30, and may fix #34 as well!
Updated default WP version to 3.7.1, disabling auto updates of core codebase

Fixes #32
Probably best to still pass wp-login requests, and only pipe wp-admin reqs
