Obtainable And Placable Challenge Doors

Enables challenge doors to be placed, used, and picked up infinitely. You can also buy them at the 2 way teleshop at the cost of 10,000 pixels and 5 teleporter cores (making it more practical to just collect whatever you find underground).

Prize - weapon damgage scales with the threat level of wherever they are placed. In other words: from doors on volcanic planets you will get powerful weapons and from doors on your ship you will get nearly useless weapons.
