New Feature - Enable Function Keys for use with Jump to Desktop

[flmbray]

Adds ability to control which keys (Keyboard Digits, Numpad Digits, and now Function Keys) are bound when registering the Jump-to-Desktop hotkeys. Prior defaults (Keyboard Digits + Numpad Digits) are maintained. User can control the setting via the Settings dialog.

Addresses the user request #190

Here's the new dialog, showing the Function Keys (F1 - F9) enabled, and the default keyboard and numpad digits disabled. (Note that I use Ctrl+Alt+Win as my hotkey modifiers, so that option is currently not auto-selecting any of the modifiers. See my PR #192 for other changes that address this issue.)

If the user has the Jump to Desktop option enabled, but no keyboard options are selected, then they will see a "REQUIRED" feedback next to the keys as shown below. If the user closes the dialog in this status, it will simply not register any of the Jump to Desktop hotkeys, as if the option was disabled.

That looks great. Thank your for you fast response. Is there a timeline when this will be available in the downloadable msi or exe?
