0.11.0

**Changes**:

- [294](https://github.com/alecthomas/voluptuous/pull/294): Drop support for Python 2.6, 3.1 and 3.2.
- [318](https://github.com/alecthomas/voluptuous/pull/318): Allow to use nested schema and allow any validator to be compiled.
- [324](https://github.com/alecthomas/voluptuous/pull/324):
Default values MUST now pass validation just as any regular value. This is a backward incompatible change if a schema uses default values that don't pass validation against the specified schema.

Modify `__lt__` in Marker class to allow comparison with non Marker objects, such as str and int.

- [291](https://github.com/alecthomas/voluptuous/pull/291): Fix `Coerce` validator to catch `decimal.InvalidOperation`.
