[emacs] remove shackle

most packages that i use have fairly sane defaults.  also, shackles
messes with magit popups a bit, and fixing it would require writing
custom functions, which i'm not down to do at the moment.  basically,
the costs way outweight the benefits right now.  i might add it again
some day though :)
