Clean up theme for better W3C compliance

There are a number of old tags in hk_theme that throw errors in the W3C validator that should get fixed, and I added bing webmaster verification that should as well be added:

add <meta name="msvalidate.01" content="39B34C79CB9947373E2134525CD68342" /> just behind google verification tag
add <meta name="yandex-verification" content="43592467d515c22c" /> behind bing validation
get rid of obsolete profile="<?php print $grddl_profile; ?>" in head tag
get rid of cleartype meta tag that is unsupported (see https://www.drupal.org/node/1717090)

change viewport tag to be more google compliant: <meta name="viewport" content="width=device-width,initial-scale=1"> Also, there is a strange occurence of additional doctype, html and body tags in the first two search box forms:

<form action="/" method="post" id="facetapi-multiselect-form-2" accept-charset="UTF-8"><div><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<?xml encoding="UTF-8"><html><body><div class="form-item form-type-select form-item-facets">
<select class="facetapi-multiselect facetapi-multiselect-field-kategorie form-select" multiple name="facets[]" id="edit-facets--2"><option disabled></option><option value="field_kategorie:15">Bezugsfreie Wohnungen (56)</option><option value="field_kategorie:11">Gewerbe Kauf (3)</option><option value="field_kategorie:7">Vermietete Wohnungen (3)</option></select></div></body></html>
<input type="submit" id="edit-submit--2" name="op" value="Abschicken" class="form-submit" /><input type="hidden" name="form_build_id" value="form-g4hptDj7G6u52vfAOcI974jEs8MwN2AoMNjPAhoMuxM" />
<input type="hidden" name="form_id" value="facetapi_multiselect_form_2" />
</div></form>

That should be investigated too.
