Blank the screen with color 0, add third color for failed logins
- Adds another color in config.def.h, COLOR_INIT - Renames the colours from numerical ones to ones with meaningful names; COLOR_INPUT for when there is content in the input buffer and COLOR_EMPTY for when the input buffer has been cleared (backspaced or a failed attempt). - Ensures XFreeColors frees the right number of colours. This is now derived from the size of `Lock->colors` rather than being an integer literal. - Makes slock exhibit the behaviour described by Markus The default colours are the same as the ones slock currently uses, with the exception of the new color, which I have set to red, as it indicates someone has either failed an attempt to unlock, or that they have entered input and erased it all.
