[ANN] alt-comment-dwim: A C-u based alternative to the built-in comment commands

Taken from the readme: This package provides comments similar to the built-in commands of the newcomment package (e.g. comment-line and comment-dwim). The difference is that the behavior of this package’s commands change depending on the number of universal arguments provided. Additionally, the commands have useful appended text (namely, todo keywords and a timestamp).
