Bitcoin.pdf: Create Page Linking To Translations
- Adds a new page linking to all translations of Nakamoto's Bitcoin
  paper, and also provides instructions for adding new translations

- Changes all links on the site that used to point directly to the
  English bitcoin.pdf to point to the new page.

- Add Spanish Translation by Breathingdog, as well as Spanish strings
  for the now page also by Breathingdog

#translate( id [,category ,lang] )
#Return translated string using translations files
#category and lang are set to current page.id and page.lang, but they can
#also be set manually to get translations for global layout and urls.
#Example: {% translate button-wallet layout %} will return the
#translated button-wallet string for the global layout file
#dynamic variables can be used as arguments
#Example: {% translate menu-{{id}} %}
#urls and anchors are automatically replaced and translated.
#Example: #vocabulary##[vocabulary.wallet] is replaced by
#/en/vocabulary#wallet when the page is in english or
#/fr/vocabulaire#porte-monnaie when the page is in french.
