Unknown format displayed on Yippy history for Snapshot copy

[blfernandezGit]

Test steps:

1. On a mac, press Shift+Command+4
2. Press and hold Control button while holding and dragging mouse cursor to take a snapshot and copy it to clipboard
3. View copied snapshot in clipboard

Expected Result: View snapshot image in Yippy History

Actual Result: "Unknown format" is displayed, not the actual snapshot image captured

Note: Also an issue with Control+Shift+Command+3

The same thing happens for URLs, I might add. There's always the link and the "Unknown format" entries.
