Add RSASS, MSR, XM2010

- Add RSASS, MSR, XM2010 normal, SD, NV and TWS versions
- SD versions have a slightly slower bullet speed as the non sd versions. Server Admins have to be careful with adding the SD versions to not hurt the server balance.
- Remove old AS50 ammo config, it is not needed any longer, also switch to the correct AS50 magazine classname.

Thx @AlwarrenSidh for the weapons.
