v0.5.0

A bit of medium-sized refactors:

• Removed entirely the science and supply system - (The fun is in simplicity! (I hope)), cards now can by purchased using energy
• Removed cost of playing cards - instead some cards get "Drain" keyword (only a few that allows to build buildings - to balance the price)
• Changed the energy system - now it stays between redraws, no limit, but player start with 0 production and need to play energy cards or build power plants to gain production again. 
• Added tooltip with more info about cards/effects.
• Made the board 2 rings larger.
• Removed tiers from market - now there are only the "fixed" and the "random" tabs.
• Added exhaustion to cards - after a card being played -it becomes exhausted until next redraw - no more unlimited loops of drawing and playing.
• Added some junk cards to starting deck
• Some fixes as usual
