Great change: new projects, new fields, new translation

Hi you all,
I started editing data.json and I made some changes:
 * I ordered the translations by code (de, en, eo, fr, it, ru)
 * I ordered the licenses by id and added two licenses (CC BY 2.5 and The Gutenberg License)
 * I ordered the alternatives by id and added some projects (Bit.ly, Google Documents, MATLAB, PayPal, Picasa, TinyUrl, Wolfram Alpha)
 * I added a template in order to ease the add of new projects
 * I ordered the projects by category and divided them by new lines
 * Mailoo, Vanity (social), ur1.ca, BitCoin (tools), JSlander, Project Khalio, AncientBeast and Cobalt Calibur 3 (games) have been added (see [bug #19](https://github.com/libreprojects/libreprojects/issues/19))
 * OpenPhoto has been replaced by PixlPaste (see [bug #30](https://github.com/libreprojects/libreprojects/issues/30))
 * Wikitravel, a project bought by Internet Brands, has been replaced by Wikivoyage, a fork of Wikitravel maintained by Wikimedia Foundation
 * I added to many projects all the parameters ("id", "category", "name", "description", "address", "licenses", "tags", "alternative", "introduction" and "source"). All parameters to all projects will be added later
 * I changed the Esperanto translation
What do you think? :)
