Title: Proxied invocation of overridable functions through call to apply `this` context

Allows overridden `custom` upload/error functions to access the inlineattach object for calling back on the `onErrorUploading`/`onUploadedFile` functions.

i.e.
```
$('.inlineattach').inlineattach({
customUploadHandler: function(file) {
var that = this;
MyCustomUploader(function(error, data) {
if (error) {
that.onErrorUploading();
} else {
that.onUploadedFile(data);
}
});
}});
```
