Pop up search window to add a CID in a data field

[redransil]

Sometimes we are going to need to reference a CID in an asset, because an asset will reference another asset but not copy its data. The easiest way to do this right now is to copy the CID and paste it into a string field.

We need a UX where:

• The user can choose a "Select Record" button
• A popup window lets the user select the data chain, and search for records
• The user can set to either look at asset or type records
• The user selects a record, and its CID is entered in the type field
• The user can click on the CID to change it, and either type in a new CID or search for another one
