Update #3 - Vaccination

Changes include:

• Set a testing capacity so only 40-55k people can be tested each day (stops the ludicrously high numbers of testing if you let it rip)
• Modified virus and restrictions to make case peaks less sharp
• Made a slight change to how people decide if they will get tested
• Added number of unknown cases to the daily change in cases UI
• Added deaths outside hospital to the daily change in deaths UI
• Increased recovery threshold again
• Implemented basic version of vaccines (between 35k-55k people will be vaccinated each day, currently only one dose is required for maximum protection and there is no decay of vaccine effectiveness)
• Made numbers in UI display commas when they are over 1k
• Changed hospital and deaths graphs to show vaccination status
• When clicking the chart buttons, new graphs will now appear instead of writing on top of already opened ones
• Made charts scale x axis better by forcing right hand side to be the current day
