GUI/Host

[Frank Marino]

I've made a few changes to the GUI, and I had to add some lines  of code to the Path Finding and FloorPlanAndTile projects, so please update these before working on them. 

The map now remains pixelated. This is especially important with our small demo map. 

The host now automatically starts listening for connections. This was for debugging, but we might want to keep it, as it's one less step. 

I removed some bugs that crashed the program when steps were taken out of order. 

Still undone:

I'm trying to get the panel to refresh with mid-move updates to show a smoother robot movement accross the map. This is still not working right. 

I'd like to take advantage of the serializability that Debarati built into the floor plan so that we can save them 

If anyone can think of any final updates that I've forgotten, please mention them.
