Issue #415 - Refactor Events to prevent continous state changes causing slowness

1. Changed how events are handled
2. Made sure of the following
   1. To Block and From Block Comparison is still value
   2. Inputs do not accept any non-numeric characters
   3. Last days/weeks/months accept decimal input (only one decimal value)
   4. The state is updated correctly on blur for each field
   5. The state of fields preserved while still on page
