initial support for jade

Replace Markup.js with Jade [1] for real templating (like expression
evaluation and sane syntax). Jade compiles directly to JavaScript which
makes it possible to only have Jade as build dependency with a tiny
runtime wrapper for the client (around 40% of Markup.js's size).

Templates are rewritten for Jade but do not use all features from Jade
(such as filters, mixins and includes) for now.

A simple requirejs-jade wrapper to compile Jade during runtime is
already included.

i18n
----

I also rewrote the i18n module and moved translation and pluralization
functions back into the module, thus decoupling it from the previous
markup language. The module now exposes:

  * i18n.translate(msgid) -> string
  * i18n.pluralize(msgid, n) -> string

I18n depends on app/config and thus has access to the user's prefered
language and exposes both function with `i18n.lang` already set. If the
msgid was not found, it returns "???" (like Markup.js).

The pluralization function replaces `{{ n }}` with the function argument
just like with Markup.js (to keep the diffs clean).
