Label the mail, clipboard, and server icons on hover and provide better GUI indications

Titles like:
Inbox
Sample Clipboard/Analysis Queue/etc?
and Jobs/Process List

respectively?

The server image should be green when processes are running and show the number of failed processes in a red icon like the mail icon does when there are unread messages.

Correction, based on the fact that the Analysis dropdown says "Create From Selected Samples", the clipboard icon pop-up text should be titled "Selected Samples" for consistency
