Update v0.1

Howdy everyone, while I get ready for the steam release, I've made a bunch of updates and fixes for the game:

1. The rounds end quicker if you run out of pegs and buckets, it will go to zero if you clear all the pegs
2. Pegs will now respawn (this is an upgrade)
3. Buckets can also respawn now (upgrade)
4. The end of round modal is more clear to what's happening e.g leveling up
5. Balls give money on death or removal (lol I need to find a good term for this)
6. Some upgrades have been re-balanced
7. Added old save warning (previously would remove old saves)
8. Fixed some issues with stat rounding (the stat values were wrong but the upgrade values were correct) basically when displaying the upgrade values, it was displaying them incorrectly 
9. Removed passive income upgrades

More to come in the next couple of days, I have a new rewards system planned, new level variations and bosses before I ramp up development for the steam release
