Decimal line items for labor hours
Now Billable Time line items on invoices will reflect actual hours of labor being billed, not just quantity “1.”  This was a workaround due to a limitation of item quantity only allowing whole integers

Nobody likes to chase after money, but the reality is it people sometimes forget to pay their bills. Invoice reminder emails will go out automatically after 30 days.

Minor layout updates
General cleanup and formatting
