Closes #1193

Summary

Following an update to the spam detection system, videos stopped working because the spam detector was expecting an Entity object rather than the Video that our media POST was passing to it.

This caused an issue where-in ->getDescription() could not be found - as Video has the description attribute, I added getters and setters into the Video class.

Testing

Test various upload types, try posting with and without a red flag failing link (e.g. bit.ly).

added scoped labels

added scoped label and automatically removed label
