Allow the administrator to define fields of type "Lookup" in Maintenance Checklists as can be done in Compliance Questionnaires.

This would then be usable in both Web Central and OnSite

An example of use case is when PM work requests are used to track inspections. and we need to keep track of the inspection device used (e.g a CO2 meter). Those devices have been put into the EQ table so that means we need to associate an EQID with the inspection while on the field. Having the correct EQID is important because associated with it are calibration information. If this EQID is incorrect, this can lead to incorrect information being provided to the lab in charge of analysing the collected samples. Manually typing the EQID is of course error prone.
