Do not deactivate-mark if region active when exchange-point-and-mark
Remove web-mode customization

- Code indent offset is subjected to personal taste, I think we should
  stick to the web-mode default, which is sensible enough, and leave it
  to the user to decide.
- `web-mode-disable-autocompletion` is no longer used by web-mode.
- As to `newline-and-indent`, I think we should be consistent across all
  major modes. And this line of code will become useless with Emacs 24.4.
Make web-mode play nice with smartparens

web-mode's auto paring is in conflict with smartparens. With
smartparens, since the closing '>' is inserted right after the opening
'<' and web-mode is not aware of that, the extra closing '>' would be
inserted. That's very annoying.
Run prelude-prog-mode-hook with CSS

I don't know if CSS should be count as a programming language, but the
utilities provided in the `prelude-prog-mode-hook`, such as
smartparens, whitespace-mode, comment annotation, are also very useful
when editing CSS files.
