Move account row to a macro

The "Connected Accounts" listing includes accounts elsewhere along with some kludged together systems (Bitcoin, Balanced). As part of #2053 we want to group the items under Connected Accounts, but the groups don't fall out along the lines of the accounts elsewhere/kludge split. Moving this bit of markup to a macro gives us the flexibility we need to knit true and kludges accounts elsewhere into the UI we want.
