small update to emacs customizations
Removed ac-complete, replaced with company mode

ac-complete is apparently a complete disaster and has not been
maintained at all recently. Company mode seems to be a much more
competent replacement than it was two years ago. Replaced.
updated lots of emacs packages

v#	renamed:    emacs.d/elpa/auctex-11.87.2/style/book.el -> emacs.d/elpa/auctex-11.87.5/style/book.el
