V1.0.1 and V1.0.2 minor changes

This is a devlog for two updates because I messed up parasite AI in 1.0.1 oops.

V1.0.1

• Opening containers with nothing now displays an "empty" message.
• Greatly increased parasite's detection range and made it wander in a chosen spot for a bit longer.

V1.0.2

• Updated parasite's code for handling multiple targets because 1.0.1 broke it.
