Fix code issues with dobryprad.pl website

Fix the following issues in the following order of importance : - customize CTA button on upper right side : change « kontakt » to « Szybki kontakt ». Include call to action line « Czy wiesz że możesz zaoszczędzić do 30% na rachunku za prąd ? » above CTA button in a bigger, blue box surrounding the CTA button. Letters in white. Box in blue. - On mobile device: "szybki kontakt" CTA button located within content pages' text does not appear fully - we need to fix this so the button is readable and appears properly. - Open possibility for user to comment below the content using disqus, and linking the website to [login to view URL] disqus’ account. - include social buttons linked to [login to view URL] social media accounts (facebook (first) and twitter (second)) on the website. Social buttons need to be clean and appearing on every page of the website. - include breadcrumbs on website - when going from one page to the other on the website, page title appears as a white blank rectangle for a second. Page title should appear properly as user enters new page. - fix possible error block message still appearing on bottom of page (received one comment from user that it was still appearing on his laptop). - ensure hreflang tags errors are fixed.
