Title: `callApi` doesn't accept Long inputs, which are needed for timestamps.

Option inputs of type Long are ignored with line Line 246 of Uploader.java:

Lines 244-256 (https://github.com/cloudinary/cloudinary_android/blob/master/Cloudinary/src/com/cloudinary/Uploader.java#L244-L256)
```
// Remove blank parameters
for (Map.Entry param : params.entrySet()) {
if (param.getValue() instanceof String || param.getValue() instanceof Integer) {
String value = Cloudinary.asString(param.getValue());
if (!TextUtils.isEmpty(value)) {
multipart.addFormField(param.getKey(), value);
}
} else if (param.getValue() instanceof Collection) {
for (Object value : (Collection) param.getValue()) {
multipart.addFormField(param.getKey()+"[]", Cloudinary.asString(value));
}
}
}
```

Long is useful for timestamps because they are very large numbers. The workaround is to pass timestamp in as a String.
