Buu's Swords 2.0

This patch fixes some more issues that people have had/brought up.

• Added a basic layer of TTT compatibility.
• Added some error checking in certain places, JUST IN CASE.
• Added ply:HasShieldType()
• Added a bunch more info the the readme, especially in the section covering DarkRP jobs
• Rewrote the movement speed system (weapon weight). Should be a lot more robust and no longer give problems this time. This also means I got rid of the UpdateSpeed function, so if any devs were using it, they can drop it now as it's not used anymore.

When updating, be sure to manually copy your changes to the config, as this update includes new config options. You will be required you to replace the old one, so having a backup is a good idea.

One user noted problems with PAC3, but most others have not. If you're having trouble with it, please contact me so we can sort it out.

NPC animation for players is still taking time to make. I apologize for the delay. However the addon should be fully compatible with Nutscript, Clockwork, etc... as long as you are using player animations over NPC animations.
