SecobMod 2013 Release.

The final .dll release. All along the point was to port seco7 as it
stood to the 2013 SDK and with this final commit I have done just that
(more if you consider the new portal gun).
So, come one come all - Source Engine Co-Operative Base Modification
awaits your modding skills!
As always remember to include the credits list found on the valve wiki
page in any modification you release using either the mod or content
from SecobMod (2013).
