Fixed bad spawns on cs_havana

Sorry, I should've done these minor spawn changes in one.
Last one.
These changes move all of the spawns on cs_havana out of the areas of the map that trap players.
There are 3 areas on the map that seem to randomly block themselves off at the start of rounds (read more in map overview here- http://counterstrike.wikia.com/wiki/Havana).

I have moved all of the player spawns that are inside these areas of the map.
