BGE Logic UI: more actuators + almost all sensors

* Matt, I'm marking some "property" rna properties that will need some speacial lookup.
Talking with Campbell we thought that it will be nice to have the lookup with autocomplete for the properties, but giving you the freedom to type whatever prop_name you want (so you can use python created properties).
That way we would still store it as a string.

Whenever the property doesn't exist (or was renamed, therefore can't be found) the property name tints in red ...
Is that possible?

* Matt: in draw_actuator_random I used a uiItemL for one of the modes. Is there another way to do that (having the label in the rna file?). I noticed draw_nodes has some cases of that as well.

* Andrea, the actuator_game property filename (in rna_actuator) is the one that needs to open the filebrowser but saving the result as relative path (or to have relative path as the default in this case)
