Hey everyone! A very sizable update that will bring a lot of joy to a lot of people. 
I managed to fix a lot of bugs that had a significant impact on performances. The resulting increase in performances is going to be very noticeable! I also worked a lot on the UI and some usability features. 
With this done, I'm going to be fully free to focus on 0.6.0 starting now!

Performances

• Very significant improvement to performances
  
• Removed auto-reload after autosave, lead to its own problems
• Fixed all (I hope) memory leaks
• Updated Bibite Vision to spread computing load
• Updated Pheromones to spread computing load
  
• Added a user setting to reduce pheromone quantity
  

Ease-Of-Use

• Page-up / Page-down => change camera scroll speed
• +/- => zoom in/out camera
