Multiplayer Update

Major changes:

- Added PvP Multiplayer (chat included), for more information read description at the main page.

- Added PC (Windows) build available for download.

Minor changes:

- Added Reshuffle Ship button, so opponent can't just memorize where your important modules are, if you use the same ship.

- Adjusted ship generator so it create ships with too few weapons less often.

- Made turned off modules darker to distinguish them easier from turned on modules.

- Warning messages no longer overlap each other anymore.

- Now new weapon is selected automatically after choosing target for the previous one.

- Shields now placed automatically in the same places when new turn starts.

- Armor are now transparent only in the center, so you can easier see where you have an armor and how many layers, while also seeing underlying modules clearly.

- Warnings now appear on top of the screen, to make place for chat in the bottom.

- Fixed bug with shield still protecting after turning off.

- Detached parts of the ship without energy are now automatically destroyed (previously only parts without command bridges were destroyed).
