Loading populations works only the first time NERO mod is activated

[GoogleCodeExporter]

To reproduce:
1. Train a population of NERO agents in OpenNERO
2. Save population
3. Exit mod, re-enter mod
4. Load population - no effect
5. Deploy - no effect

For comparison, start NERO from scratch, and load the same population file. 
Hitting deploy makes the population run.

Yes, last time I checked, this was still the case.

See r1410 and r1413 for the changes that have fixed this in my branch. They're 
not the cleanest revisions unfortunately but the gist of it is that I remove 
all existing agents when either load or deploy is called, and then do the 
actual load or deploy with a new set of agents. Also, I made a change in my 
branch so that all loaded/deployed agents are spawned immediately rather than 
waiting for future calls to spawnAgent.

I think at some point just merging my branch back into trunk will be a nicer 
way to get the changes that fix this issue, since the code in my branch also 
includes a bunch of work I've put in to allow RL and RTNEAT agents to coexist 
in NERO.

the branch has been merged into trunk (and should probably be re-created now).
