Update Webmaker description on Wikipedia

[KevZawacki]

The Webmaker blurb on Mozilla's Wikipedia page (http://bit.ly/1dKf6UY) is outdated. It reads:

"Mozilla Webmaker is Mozilla's educational initiative. Webmaker's goal is to "help millions of people move from using the web to making the web." As part of Mozilla’s non-profit mission, Webmaker aims "to help the world increase their understanding of the web, take greater control of their online lives, and create a more web literate planet."

Proposed new language:

"Mozilla Webmaker is a free, open-source and independent Android app that aims to help individuals of all skill levels create original content on their smartphones [1]. The beta version of the app was launched in June of 2015, and is part of Mozilla's efforts to foster universal web literacy and empower local content creators [2]. The app was developed after research in Bangladesh, India and Kenya [3], and is available in four languages: Bangla, English, Indonesian and Portuguese BR."
