1.03: Easier Addition of Odd Keys Like Tab

Added: any key that appears in chatter log now has an [Edit] button that, when double clicked, adds it to the configured key list and jumps to that link in the "Configure Keys" tab (note that even keys not specifically customized will still appear in this log if the Global Chatter Threshold is low enough to catch it).

This was suggested in issue #4 as a solution to the question of how to add non-letter keys (such as the Tab key) to the configure list.
