Fix startup for Emacs 24.4
Big update to make packages compatible with 24.4

I'm sure I missed some.
Auto-save, take 1
Let's try powerline!
Use the new `load-prefer-newer` option
Some basic config for eww--let's see if I use it
Start full-screen
A little bit of org-capture (still WIP)
No more cursor blinking
Render HTML mail using shr!

So much nicer
Oops
Fix package auto-installation
Adjust some repos
Workaround for my pet 24.4 bug
No blogging for now :)
