[patch] Editable Checkbox Groups in user defined forms should display the field's name, not a pointless number

[DanielVF]

Checkbox groups in user defined forms are currently emailing you numbers for the results. Your emails look like:

Areas of volunteer interest:1,2,3,4,5

They should look like:

Areas of volunteer interest: Distribute food, Donation pick-ups, Office support maintenance, Retail/thrift store, Recreation special events, Data entry for THCO

This patch fixes this.
