Text wraparound

[araml]

Add proper text wrap around for the lyrics (including word wraparound).

(Use ncurses pads?) It should:

• support a max width of 80 cols
• change pad to a smaller one if the term get resized to < 80 cols
• wrap words if they don't fit in the current line
• wrap on letters if a word is longer than 80 cols
