Add total launches per day

[mjennings061]

As a GUR bitch, I want to have a summary of total launches and hours for each day, so that I do not need to calculate it for the GUR.

Dev notes

• [x] Create a function to calculate total launches for each day
• [x] Calculate total hours for each day
• [x] Display totals in a table, with other GUR tables
• [x] Display the last 10 days
