(QoL) Quick Import from PlanSwift

Currently in zzTakeOff, to import a PlanSwift project, you have to go to the folder location and import the job folder.

Planswift can email a "PlanSwift Job file type", and once clicked will import it into Planswift.

If zzTakeOff can also use this file type, it could make the process easier.

This is helpful when having outsourced take-off workers (That has Planswift), sending Planswift files. And can make it a shortcut instead of import it into Planswift, then importing to zzTakeOff.
