remember what workunit we exit from. about pyrit HOT 1 CLOSED

Pyrit does not "remember" the workunits that are already computed but checks 
for that
in the moment it reads it's specific key. It does not re-compute workunits that 
have
already been computed before.

You'll see that on the second run Pyrit skips some units and finishes e.g. at 
75% (in
case you did 25% on the first run).

I'll take care that the numbering is more clear in 0.2.5
