Summary: When a user requests to read the contents of an attachment, only allow the request if there exists a cell in an attachment column that contains the attachment and which they have read access to. This does not cover: * Granular write access for attachments. In particular, a user who can write to any attachment column should be considered to have full read access to all attachment columns, currently. * Access control of attachment metadata such as name and format. The implementation uses a sql query that requires a scan, and some notes on how this could be optimized in future. The web client was updated to specify the cell to check for access, and performance seemed fine in casual testing on a doc with 1000s of attachments. I'm not sure how performance would hold up as the set of access rules grows as well.
