DNA flow possible error

[Numsgil]

I'm not 100% sure on this one, but I found a similar bug in the C++ source.

THe CurrentFlow variable wasn't being reset to CLEAR when a new bot began executing.  The possible result of this could be bots that inherit the flow control from the previous bot that was executed.

For Instance:

Bot 1:
start

Bot 2:
10 .up store

The rules should prevent bot 2 from executing that store.  Instead it's allowed because the CurrentFlow flag was still set to BODY.

Nice catch.  This does indeed appear to be in 2.4X.  2.42.3 will have the fix.
