Enable the mouse for selecting an item from the list of words

[ManiacDC]

The mouse should be usable to select a word from the list of words. This should enable better usability with touchscreen devices.

Logic, still need to add option to disable: https://github.com/ManiacDC/TypingAid/commit/a56fdb1483612f63dc7f2363dae403404ddb8227

Also, I want to change the cursor to a hover finger when enabled AND over the listbox.

You'd thinking changing a mouse cursor should be trivial, right? I spent much too much time reading on this. Very few people seem to know how to do it correctly. Changes committed to use the hand cursor when hovering over the listbox. https://github.com/ManiacDC/TypingAid/commit/666075f4e51f1437eeacbb99b9ca43714b09760b

Added to Settings window https://github.com/ManiacDC/TypingAid/commit/f26fb5017f48b899b6880ccddd79c79472c20a20

I changed the setting so that it specifically reads "Single Click", and when it's unchecked, a double click will complete the word.

Removed some extra work the cursor code was doing Fixed a slight delay in changing the mouse cursor when drawing the listbox https://github.com/ManiacDC/TypingAid/commit/733b1add42e8391d4ed28399496670b17887390d

Had to add code to monitor the scrollbar to make sure the numbering worked correctly Had to rewrite the click code because spamming the scrollbar buttons was still causing problems https://github.com/ManiacDC/TypingAid/commit/272beb2c8e78f55784c6f466c1428bd6891a0b0f

Clear the timer when I start scrolling so that it doesn't switch on me if I start scrolling before the timer triggered. https://github.com/ManiacDC/TypingAid/commit/492c6159f81e7d1c7af7210da32c0cf35503f255
