First pass at Windows installer

* vip-init.bat prompts for UAC and launches the powershell script
* vip-init.ps1 is the powershell script that sets everything up

When you double click a powershell script in Windows, it just opens in a
text editor. When you double click a .bat file it runs.
Pin WP-CLI to v0.12.0

Keeping WP-CLI on v0.12.0 so we always know what version we're on. We
can bump it manually in the future and fix  stuff that may break. Fixes
#13
Fix Vagrantfile

* There was some brokenness when we set the hostname.
* Maps the MySQL port locally
Update README with Windows instructions

The Windows installer works now, so we should update the README to
reflect that
Merge branch 'master' into windows

Conflicts:
	Vagrantfile
Set a hosts entry for vip.dev on the VM

This fixes wp-cron and probably some other stuff as well. wp-cron
sends a request to wordpress so another thread can handle cron, but if
the server doesn't know what vip.dev is, this won't work

Fixes #40
Automatically activate recommended developer plugins

Fixes #30
Add a WP-CLI config file

It's nice to be able to use WP-CLI anywhere inside the VM, so we're
adding a config file with the path. In order to use the config file
everywhere, I've also added an alias for the `wp` command with
the full path to the config

Fixes #15
Move WordPress.com compat stuff to vip-config.php
Make error logs available to host OS

Fixes #12
Clean up vip-init
Mirror Batcache config

Fixes #6
Stop the weird wp-content dance

Before this, puppet would delete the www/wp/wp-content directory because
we don't need it. Since it's in version control, `vip-init` would add it
back during the `svn up`. So every time you ran `vip-init`, it would go
through the process of readding wp-content. This fixes that.
Install apc
Terminology change
Bump wp-cli version
Add functions-mobile.php handler

Use the nginx puppet module's built in support for removing the default
vhost
Set the upload limit to 1GB

We need the following pull requests to be accepted in the nginx pupet
module before this will do anything:

* https://github.com/example42/puppet-nginx/pull/40
* https://github.com/example42/puppet-nginx/pull/41
Configure nginx for max upload size of 1GB
