Allow start time offset

New test branch to add a feature to allow an offset to be used with the
start time (so for an event starting at 1pm for example, you can show
it as starting at 12:30pm - useful for games where people are always
late).
Corrections

Forgot to pass the startoffset value back into the URL when it’s
rebuilt. Was also checking the wrong value when building the variable.
Merge preparation

Updated minor version number to 1.4, added Keon Park as a valid
location for the WCBA.
