Misc additions

- Move aliases.el to lisp folder of its own

- set dired-listing-switches

- set package-archives

- set electric-pair-mode

- set c style params (probably to be changed...)

- Add ecb options

- Add .emacs.d/lisp to load-path
Add ll alias to eshell
Fix previous ignores in .emacs.d, add elpa to ignore list

ELPA is a massive repo of stuff, no point duplicating it in our git repository
Get rid of .emacs.d/aliases.el, this was moved in a previous commit.
