Add triggers for Valid until on TF and Trainer

[atlasjen]

Change "Trainer Certification Valid Until" to be 1 year from "Last Trainer Program Agreement" Change "Facilitator Certification Valid Until" to be 1 year from "Last Facilitator Certification Agreement"

[deb761]

Those two fields are already formula fields.

adding note that this was properly implemented as I intended vs what i wrote above. Trainer Cert Valid until is based on Trainer Cert Agreement Date.
