#1854 CompileBranding shouldn't consider line breaks inside tags as relevant

[Luca Olivetti]

When compiling the branding section inside an extension, if you specify an image file on a line by its own, if will look for a filename with the line breaks, e.g.

<main_logo _delta="define>
   my-extension/images/my-logo.png
</main_logo>   

the file it looks for is \rmy-extension/images/my-logo.png\r which of course doesn't exist and the error message is misleading (it's not easy to see that the filename is wrong since one mentally removes the line breaks).
Line breaks right after the opening tag and right before the closing tag shouldn't be significant.
