WIP: Documentation revamp
this brings some changes for the 0.10 bitmask release:
- remove oblivia, add colnodo.
- introduce optional javascript detection of the platform in the landing page; downloads bundle by default.
- make the icons in the install landing page download the bundles; add links for more detailed pages.
- greatly simplify bitmask/linux install page.
- separate debian/ubuntu install pages.
- add links to alternative install methods (pip, git).
