WebLaunch v2.1

* Updated Wave logo to the new SVG-based logo that the v0.56 update
brings
- Removed some redundent code
+ Improved performance
+ OpenSans is now used as the font on launch pages, rather than the
broken old font which fell back to an ugly serif font. (OpenSans is
locally hosted for better privacy, with specially optimized
WOFF2/WOFF/TTF formats)
