Custom fields

[riek-lt]

For donation pages on a per-marathon basis, have custom questions via open text/checkbox/selection.

Examples:

• Team Green Gaming can have a selection box with locations for trees planted
• Marathon X can ask "Tick this box if you allow us to send you a newsletter 4 times a year"
• Marathon Y that wants freeform text for any reason, like "random donator gets to name my baby, what's your pick?"

Current build has checkboxes and freeform inputs, select menus to come later.
