Swirl Secondary Riffle Fire

We are trying out a new secondary fire for the riffle, where it unloads a clip at a very high rate, however it has a very large spread, and your movement is slowed down while firing with the secondary. Recoil is also applied to both fire modes. With the exception of the recoil, these initial attributes of the rifle secondary were ported from the Tremulous gpp mod Edge. Below is the link to the relevant commit of these changes:
