Sync folder disable option was not passed correctly.
Add winrm to the config_builder model

This adds the winrm attribute to the config_builder, so that the user,
password and other settings may be specified in a separate winrm.yaml,
when using the WinRM communicator.

    winrm:
      username: 'administrator'
      password: 'vagrant'

Merged with a couple touch-ups to remove uneeded code.

Signed-off-by: Charlie Sharpsteen <source@sharpsteen.net>

Closes #26.
Implement modle for SSH configuration

The skeleton of the model necessary to configure SSH options has been around
for a while. This patch replaces the comments with functional code.
Add all the box config options to the VM model

Added every box related configuration option listed in the Vagrant docs:

  http://docs.vagrantup.com/v2/vagrantfile/machine_settings.html
Update CHANGELOG and version for 0.11.0
Add vmware workstation support.

Use a generic vmware model to support fusion and workstation. A generic
vmware provider will pick the appropriate provider. A warning message is
generated regarding missing plugin if vmware provider is requested and
neither fusion or workstation plugin is loaded.
Dynamic YAML config by processing ERB first

The yaml configuration files are processed by ERB first. This allows
slightly more dynamic configs, such as support of environment variables
for vagrant vm/provisioner settings:

```yaml
---
  provisioner:
    - type: puppet
      manifest_file: <%= ENV['VAGRANT_MANIFEST'] || 'init.pp' >
```
Update README to reflect some of the new features.

The README examples show:
* yaml_erb loader.
* vmware provider.
* synced_folders.
* support for boxes.
