First fixes! — Farming Isles Steam update #503328

The following are the first few fixes to Farming Isles. - Nerf Corn selling prices and yields. Selling from $7-$11 > $5-$7, now yields 2-4 corn. - Fixed the Farm Market to properly update the selling price and multipliers. - Temporarily removed Solar Panels from the structures as it can cause an issue with the save file (saving and loading a few times will result in loss of structures on other Isles). Working on a fix to bring it back. - Increased camera base and while holding 'left shift' move speed. - The Vandal attack button will now move to the next structure that is under attack. - Updated pause menu to now show the keybinds. (Yes... the keybinds still show when quitting game. Will be fixed next update). More updates will be coming to improve QoL and gameplay. Happy farming!
