Implement html/rest.js gateway which handles HTML Restbase responses

Refactor existing Restbase gateway and extract shared logic into
shared Restbase provider. Also introduced new createNullModel()
which defines an empty preview model.

Additionally improve naming in new gateways/formatter so function
names are more explicity.
 * Htmlize() became formatPlainTextExtract() as it should be used
   only with plain text extracts
 * removeEllipsis() became  removeTrailingEllipsis() as it removes
   only trailing ellipsis.
 * src/gateway/index.js defines gateways by configuration name stored
   in extension.json
