v0.6.0 - skill leveling overhaul

New version of Skilllwood has been released. 

Most important thing done - skill levels now actually matter:

• While leveling up within tier player gets bonus to damage to target objects (trees on lumbering, deposits on mining)
• While going to another grade player something like prestiging happen, player gets 1.5x more damage but uses 1.5x more stamina. That leads to less hits for the same result (in future going next tier won't happen automatically)
• Considering hit stamina now depends on skill tier and thanks to Letros comment from reddit now usual hit and perfect hit doesn't influence stamina required for hit. Hitting green zone on hit bar only increses the damage

Also:

• Hit stamina overall rebalance
• Fixed a bug when you can spam several hits in a row. Thanks to Sammy Flemington for discovering it!
• Fixed a bug when game crashes after maximum fireplace level. Thanks again to Sammy Flemington for discovering it too! (the same comment
• Fixed a bug when player can build the bridge several times if they have enough resources
