Fixed very weird bug.

Okay, let me get this straight:
- Properties actually don't have unique names
- Yet the official Valve-code accesses the properties by name
- Even for properties that aren't unique.
- You need to remember something like the "path" to access them unique.
- I haven't found any hint for this in the official code
- Instead of ~300-400 properties an entity has now >1000 properties

I wouldn't have guessed this. The time I've spent to find this is
waaaay too long. </rant>

If you worked with properties: The names might have changed from, for ex:
"a" to "b.a".
