Build #9 - Critical/Stability Chance + Upgrades

All upgrades purchasable should be working now

Upgrades allow adding processes at every tier (patch/minor/major)

Idle bonuses from upgrades should work

Production maxes are now displayed in inventory for reference (which determines your offline progress)

Stability chance has been implemented - keeps your mining sites alive for longer

Critical chance has been implemented - adds to the quantity of things received, e.g. mining critical chance guarantees an extra ore per 100% critical chance
