lesspipe, colored man pages, and get rid of most

Lesspipe differs from distribution to distribution, so this adds more
checks to try and apply lesspipe properly in all distros.

Add an alias with all necessary checks to ensure man pages work in any
circumstance, all thanks to http://unix.stackexchange.com/a/6357

And at last remove most as a pager, I don't really use it anymore.
