DDMAL/libmei — Issue #43: Set Mixin Value

When a mix in value has already been set for an element and one calls the mixin set method, the current attribute value is not overwritten.

To recreate bug:
Construct a note, set a pitch, then try to reset pitch value.

```
Note *n1 = new Note();
n1->m_Pitch.setPname("c");
n1->m_Pitch.setPname("a");

"a" == n1->m_Pitch.getPname(); => FALSE
```
