APIs missing: Document Name
The Sketch document name is not available in the current implementation.

The only way to find it is currently via:
```
var sketch = require("sketch");
var document = sketch.getSelectedDocument();
if (document.path) {
    documentName = normalizePaths(document.path.split("/").reverse()[0]);
    documentName = documentName.replace(".sketchcloud", "");
    documentName = documentName.replace(".sketch", "");
}
```
