Title: 'clean' seems to be ignored

I'm using the following:

```
middleman: {
options: {
},
server: {
},
build: {
options: {
command: "build",
clean: false // This does not work
}
}
}
```
with:
`grunt.registerTask('build', ['middleman:build','sass','concat']);`

Unfortunately, it continues to 'clean'. This commit fixes this behaviour and restores the Middleman default.
