Not Planned JB - Change maps to updated versions

[RIDTHEMID]

I think there would be a lot to gain from updating current versions of most maps. I have a lot of these newer versions in my maps folder (the steamapps folder) so if that's all that is necessary then I can send the files. The maps that I believe could gain the most from an update are jb_minecraft, jb_sg_dojo, jb_clouds, and jb_spy_vs_spy.

Let me know your guys' thoughts and if there are specific maps you know have better updated versions.
