Update weapdraw.lua

[zhivotnoya]

Changed code from cumbersome check code, to just checking for variant and switching to opposite. Also makes it easier to implement new holsters if others are added to EUP by simply putting variants in config file and not having to add to logic code.

Describe Pull request
Code was changed to facilitate checking variant pairs from new config.lua. Then simply switching the componentID based on the current componentID. So in the config, as an example, I have:

[205] = 204 -- Full to empty
[204] = 205 -- Empty to full

This way you can simply edit the config and not have to change the cumbersome logic in weapdraw.lua.

I'll go thru and remove the variables that aren't needed any longer. I'm checking my code now.
