[Geneticd-devel] Some fixings and adds.

[Jonny M. <jon...@ni...>]

I Finally added the TRAM command, that adds a random brust of newborn agents 
each N turns.

I had grown sick and tired of having to put a \r\n after each print in Core 
Commands (and the like). So I decided to add it automatically. A method in 
GStream called addEol( bool ) controls if print and vprint have to put an 
extra end of line character(s). 

I also secured the locking of master engines: when there is interaction with 
a slave, only that slave is locked, but when the engine needs to talk to all 
it's slaves, or has to change it's internal data, now the master locks.

I added a GeneticEngine::cleanup virtual method that is called when a free 
command is issued, just before deleting the engine. This lets the master to 
try to free safely all it's slaves before entering the destructor (and having 
the engine space locked).
