Custom Rig, New Beam, New Socket, Modified Grappl

Testing with admin on porting custom rigs and we can! Starting off with
custom UT3_MALE. No textures, so all white

New beam. Removed extra effects to create only one beam, colour is
greenish

New socket for beam to connect. No longer DualWeaponPoint, using
GrappleSocket instead

Grapple dynamics modified slightly

Also uploading new level along with entire config folder for
consistencies.
