Stupid formatting for Checkboxes

Added some extra divs so there can be checkboxes on the side when
attempting to create a new account.. The divs have to be placed this way
due to whitespace stuff.. It's a pain./
Added Random Username placeholder

Added random usernames for the username placeholder on the create
account field.
Added DailyIntake Macro Calculation

Added the macro nutrient calculation to the daily intake page. It was
only doing calories beforehand. It currently also does not allow
user-specific fat/carb/protein splits.
