Fixes missing images in big website page (issue 4964041)

[PhilEHolmes]

Reviewers: Graham Percival,

Message:
Please review.

Description:
This is an updated patch to put the missing image files back into
http://lilypond.org/doc/v2.15/Documentation/web-big-page.html#examples.

It adds an extra element to the path to ly-examples (web/) which fixes
up the links in web-big-page.  It does the same with the css address.
These extra elements are then parsed out with postprocess_html.py and
website_post.py.  The latter file change is the new feature of this
patch - it ensures that the split web pages are valid after make website
and also make doc.  I have used this patch and compiled from scratch and
see both web-split and web-big have the example images and use the style
sheet.

To test this.  Apply the patch.  make website - do you see images and
styles in /lilypond-git/build/out-website/website/index.html.  make;
make doc.  Do you see images in web-split and web-big?  If these are
yes, then the patch is OK.
