Always generate browserconfig.xml

[phbernard]

When the user chooses to not place the favicon files in the root directory of the web site:

• browserconfig.xml is not generated.
• The IE11 pictures are declared directly in the HTML code.

However, this is not necessary. browserconfig.xml path can de declared. For example:

<meta name="msapplication-config" content="/path/to/browserconfig..xml" />

This would save a few bytes of HTML code.

One exception: the user may enter a kind of template engine directive as the path (eg. <?php echo $icon_path ?>). This declaration will work in the HTML code to copy/paste, but the generated browserconfig.xml will probably be considered as a static file, not to be processed by the template engine. In that case, it will be somewhat corrupted.

This scenario should be taken into account.

Fixed and deployed a minute ago. This is code 0.7.
