Number system changes and bugfixes

Hey Land Drifters!

Making some progress on a new feature and making good progress, but in the mean time I wanted to tidy some things up.

Build 0.3.45 -Number system has been reworked and is more efficient. Rounding issues should be resolved. Numbers over 1000 do not show decimals. Numbers reaching 100k will show "k", and "M" for 100M. -Fixed issue with sounds getting queued when no audio devices were available. -Fixed bow/first quest achievement in collection section. -Fixed rare quests being re-assigned on reload in some cases. -Fixed combat abilities not being unlocked when level was reached until reloaded. There's now a pop-up to let you know.
