favicon.ico path customization

[AndreyAkinshin]

The default template contains the following line:

<link rel="shortcut icon" href="favicon.ico">

However, if we put a favicon.ico file in the root src folder, it will not be copied to the output folder. We also have the SourceFoldersToCopy parameter in docnet.json. It would be nice to have a way to customize path to favicon.ico and copy the corresponded file by default.

DocNet indeed copies folders in SourceFoldersToCopy and .md files in the source files and the files in the template folder and that's it. It doesn't copy a favicon.ico file. I didn't add that as it was a simple thing to add later on, but agreed, it should be an option in the docnet.json file so you can specify it and it gets copied over after each build. Good point!
