return wrap-up to default behavior

[lakruzz]

It says that it add all the work from the working area, but you actually have to run git addyour self!

in relation to a discussion about wrapup, I removed the default behaviour of adding everything when the command is called. wrapup --hard will auto add

[groenborg]

Wrapup will be changed to the previous default behavior where it automatically adds all changes. Hard will be removed, and a "skip-add" added in stead.
