Cannot select earlier year than 100

[quorth0n]

Using the date picker to select a year earlier than 100 will cause the date picker and currentDate to loop back to 1999, and the address to the intended /map/0099/.... However changing the date picker again will cause the URL to update back to /map/1998/.... Manually entering a year earlier than 100 in the address bar will cause the date picker and currentDate to be 19XX, where XX is the entered year.
