Revised logos for the website

Here are some revised logos for the website. I have also added the GitLab logo. Some logos are currently loaded via a corresponding link from the respective websites. For data protection reasons and to avoid problems with changed links, I suggest providing the logos locally. The linking would then change as follows.

Old linking:

  <div class="logos">
   <p><a href="http://www.lazarus.freepascal.org"><img src="./pic/lazarus_produced_logo.gif" alt="Lazarus Logo" height="57" width="125" ></a></p>
   <p><a href="http://www.ffii.org"><img src="https://demo.ffii.org/banners/bsod7s_88x31.en.png" alt="EU-Council segfaulted" height="31" width="88" ></a></p>
   <p><a href="http://sourceforge.net"><img src="https://sourceforge.net/sflogo.php?group_id=2174&amp;type=1" width="88" height="31" alt="SourceForge.net Logo" ></a></p>
  </div>

New linking:

  <div class="logos">
    <p><a href="https://www.lazarus.freepascal.org"><img src="LogoLazarusSplash.png" alt="Lazarus Logo" width="160" height="107"></a></p>
    <p><a href="https://ffii.org"><img src="LogoFFII.svg" alt="EU-Council segfaulted" width="40" height="48"></a></p>
    <p><a href="https://sourceforge.net"><img src="LogoSourceForge.svg" width="160" height="30" alt="SourceForge.net Logo" ></a></p>
    <p><a href="https://gitlab.com/freepascal.org"><img src="LogoGitLab.svg" width="160" height="50" alt="gitlab.com Logo" ></a></p>
  </div>

Here is a screenshot with the new logos.
