Dev Build Update V0.02.

I haven't tested anything, but felt like I had to release an update, even if it's half baked.

* Updated something.

* Dialogue system, use talk command on any NPC by their nickname.

* Sentries, Dispensers, Teleporters. Sentries keep the area clear from enemies during the wait command, and dispensers heal and replenish resources also during the wait command. Treat the teleporters like a new exit direction, just type "go teleporter" in the same room where the entrance is.

* Sapping buildings. (Currently just let's you destroy sentries when targeted by them. Though you can just ignore them as if the sentry is not there.)

* Scoreboard command. Probably broken?

* Don't remember what else.

* Everything else is broken. Enjoy.
