Single attachment column type

[mike12345567]

Description

Adding a new column type for single attachments. This will be stored as the same shape as the current attachments, but as a single object (instead of an array). Having this new type will allow having columns with a single attachment, simplifying validations and bindings.

After discussing with @AndyWhann and @aptkingston, we are also changing the current attachment column to use paperclips icons, to match usages in the design section.

We need to add attachmentsinglefield to componentStructure.json as otherwise it won't appear as a possible component to add.

Few more bits to review but have a screaming baby to attend to! So here's some initial feedbacl.

The existing attachment list uses a clip instead of the folder we use in the data section. Would you use the clip as well for this new column as well?

LGTM other than that one question 👍
