Title: Add block_device_mapping support (cleaned up and re-req'd)

Support the block_device_mapping attribute when creating a new ec2 instance.

Example:

```ruby
aws.block_device_mapping = [
{
:DeviceName => "/dev/sdb",
:VirtualName => "ephemeral0"
},
{
:DeviceName => "/dev/sdc",
:VirtualName => "ephemeral1"
}
]
```
