Integrate a list of notices for newbie users

[alexvorn2]

Integrate a list of possible warnings and notices for the power-user (admin) if some problems or security thread occur, or to check if the site was infected with viruses and malicious .php files...

Example:

• Notice: GD Graphics Library is not installed, install this so the images could be resized
• Notice: Your site is not giving search engines the right to index the site, please consider changing the settings.
• Warning: An unknown file mail.php is in the site main directory, please check if you are not infected.
• Notice: Your site files permissions are set to 777, please change to 644 or 640, your site is in a security thread.
• Notice: Upload folder is not writable, please change permission to 755 for the upload dir.
• Notice: Please use a caching file plugin to make your site load faster than ever.

I am not sure this should be added into core as it is for "newbie" users only. I think this is definatly plug-in territory. Now, I do think that would make a great plug-in, I think the health plug-in is on the right track.
