Add a colour-coded on-screen-keyboard in Liedle

[Destiny-02]

Add an on-screen keyboard below the tiles. The keyboard should have the letters A-Z, a delete key and an enter key. Make sure each tile is hoverable.

• Each key is initially light-grey
• A letter corresponding to a green tile with the same letter should also be green
• A letter corresponding to a yellow tile with the same letter should also be yellow
• A letter corresponding to a dark-grey tile with the same letter should also be dark-grey
• If two tiles with the same are coloured differently (this is possible due to the 8% chance of colouring the tile incorrectly), then colour the tile red.

This will provide an alternative input method for the user to enter the words. It will also be easier to see which letters have already been guessed and which letters have conflicting information.
