cp_roadblock a3

alot of changes made.

Some layout changes, almost implemented train at last and some new flanks.

Note: I forgot to change filename before recompiling, but after a 30 minute compile I couldnt be bothered to do another compile just to change the name, sorry if you have downloaded the previous version.

In the excitement of this map almost at a1, I appear to have forgotten a few things.

-Added pickups at last
-fixed a mistexture
-fixed a spelling error
-adjusted cap times
-compiled not in fast
-got screenshots
