Detective GUI, version1.0.0.3 bug fixes

I would have liked to wait further before release, but I identified a very annoying bug that I wanted to fix.

Here we go:

• major slow downs in most level the longer you stayed. I had left a generator item producing illimited new instances...
• you can no longer be stuck in world 1 if you go too soon in secret level, teleporter gets unlocked
• conditionnal help of world3 level1 appears much faster (still it won't appear for most players, as intended)
• World 5/-6 clue is phrased better

I hope I can take a little break before next fix batch, if no terrible bug is found
