Mostly cosmetic changes to some plugin descriptions in the manual: 1) In main.tex - don't mention chip8 games in the Player manual and give the correct path to the viewers directory. 2) Correct wrongly placed 'end' in zxbox.tex and remove link to the wiki as this chapter is based off of that page and there is no additional information on it. 3) Let long lists of button names break so they don't overlap with the next column in the pdf - blackjack, bubbles, demystify, flipit, logo, oscilloscope, pegbox, rockblox1d, rockblox, rockboy, sliding puzzle, snake2, solitaire, sudoku. 4) While at it, break long (code) lines in bubbles.tex. 5) Additionally exclude lines which showed only 'n/a' in the button tables for a specific target - pegbox, sokoban. 6) Use 'fname' to mark a path in disktidy.tex, also simplify the button table. 7) Use 'ButtonHold' in doom.tex.
