Remove break-all and font-size from guides tips

Sidebar text that appears when hovering over each part of package.json has poor readability. These changes improve it; see comparison:

* Before: http://i.imgur.com/l3RLjJW.png break-all word wrap makes text too difficult/confusing to follow, large font size attempts to squeeze too much text in too little a space
* After: http://i.imgur.com/r2meRpF.png eaiser to read; lines are not broken mid-word and smaller font size allows for more comfortable reading
