General instructions to run on any system

[tpapastylianou]

Great little game! Well done!

I just wanted to point out, the instructions (and code!) seemed very mac-specific, so I wasn't sure if this would even work on a non-mac system.

I can confirm I managed to get this to run on linux, but there was a lot of trial-and-error involved to figure out what the game was expecting in place in order to run.

I think you could probably add a small section in your README with simple instructions on how to get this to run normally from within a julia environment (e.g. something like 1. "install these packages", 2. "start from the root game directory, 3. push! src to your LOAD_PATH, 4. import PaddleBattle, 5. run with PaddleBattle.julia_main([""]) ).
