Cosmetic and Organizations Changes

Re-ordered buttons on home page, changed description of desktop site in
the footer, added suppliers to organizations, and made it possible to
search organizations and only return a certain type of organization.

Also made the address that the search form submits to more
sensible/compatible (you can now click search on organizations with
nothing filled in and get results, for example).

Added a text file to the root of the repo that has the full
organizations query in it, just so I don't have to delete all the
backslashes from its text whenever I want to change and test it outside
of PHP.
