Eliminate preprocessor usage in html.css.

We move the content of |#if ENABLE_INPUT_MULTIPLE_FIELDS_UI| to
themeInputMultipleFields.css.

We can remove |--define| and |--preprocessor| options of
make-css-file-arrays.pl, and remove preprocessor.pm.

Remove usages of jquery and add sugar.js from garden-o-matic.

Use sugar.js to replace usages of jquery and replace any extraneous
uses as well. Didn't touch the custom event stuff (bind/trigger) or
the tabs UI code. Those will naturally go away as we port things to
polymer. Kept this patch for mechanical simple changes.

The only non-mechanical bits are $.param --> base.queryParam and
fadeIn/fadeOut --> element.animate.
