TLLITs Gmail PDF Mailtolink Fixer

Fixes the issue with Gmails PFD-viewer adding HTTPS:// to all mailtolinks causing them to fail.

This extension fixes an issue with gmails PDF-previewer which causes mailto-links not to function correctly, for instance if the pdf contains the following mailto-link: <a href="mailto:test@test.com"> gmails PDF-previewer changes that to <a href="https://mailto:test@test.com"> which results in opening the webpage "https://test.com". This extention removes the "https://" from the mailto-link and makes it work again. NOTE: This issue only occurs when clicking on a mailto-link when viewed from gmails PDF-previewer. The mailto-link usually works fine if first opened in an external PDF-program (ex Acrobat Reader).
