Added regions and functions to support timeclock and dashboard methods

Trying to follow the original layout of ShiftPlanning.cs I have added regions and methods, including robust intellisense commenting, for the following API functions that exist but weren't supported by the CS SDK:

dashboard.onnow()
timeclock.clockin(employee)
timeclock.clockout(employee)
timeclock.clockout(employee, notes)
timeclock.status()

All of these additions have been tested and verified as properly functioning against my organization's ShiftPlanning account.
