Lock CSS background-image url() rewriting in the parser test

background-image is already captured and rewritten through the style/CSS
url() path, in both an external <style> block and an inline style attribute,
with the URL unquoted, double-quoted or single-quoted. Extend the offline
parser test to cover all of these so the behavior stays locked.

+It will not follow links located in higher directories, too (for example, <tt>www.example.com/gallery/flowers/</tt> itself) because this 
 might cause to capture too much data.<br>
 <br>
 This is the <b><u>default behaviour</b></u> of HTTrack, BUT, of course, if you want, you can tell HTTrack to capture other directorie(s), website(s)!..
 <br>
-In our example, we might want also to capture all links in <tt>www.someweb.com/gallery/trees/</tt>, and in <tt>www.someweb.com/photos/</tt><br>
+In our example, we might want also to capture all links in <tt>www.example.com/gallery/trees/</tt>, and in <tt>www.example.com/photos/</tt><br>
 <br>
 This can easily done by using filters: go to the Option panel, select the 'Scan rules' tab, and enter this line:
 (you can leave a blank space between each rules, instead of entering a carriage return)<br>
-<tt>+www.someweb.com/gallery/trees/*<br>

 - the <tt>+</tt> means "accept" and the final <tt>*</tt> means "any character will match after the previous ones".
 Remember the <tt>*.doc</tt> or <tt>*.zip</tt> encountered when you want to select all files from a certain type on your computer: 
 it is almost the same here, except the begining "+"<br>
 <br>
-Now, we might want to exclude all links in <tt>www.someweb.com/gallery/trees/hugetrees/</tt>, because with the previous filter,
+Now, we might want to exclude all links in <tt>www.example.com/gallery/trees/hugetrees/</tt>, because with the previous filter,

+<tt>+www.example.com/gallery/trees/*<br>
++www.example.com/photos/*<br>
+-www.example.com/gallery/trees/hugetrees/*</tt><br>
 <br>
 You have noticed the <tt>-</tt> in the begining of the third rule: this means "refuse links matching the rule" 
-; and the rule is "any files begining with <tt>www.someweb.com/gallery/trees/hugetrees/</tt><br>

 httrack \- offline browser : copy websites to a local directory
 .SH SYNOPSIS
@@ -98,15 +98,15 @@ httrack \- offline browser : copy websites to a local directory
 allows you to download a World Wide Web site from the Internet to a local directory, building recursively all directories, getting HTML, images, and other files from the server to your computer. HTTrack arranges the original site's relative link-structure. Simply open a page of the "mirrored" website in your browser, and you can browse the site from link to link, as if you were viewing it online. HTTrack can also update an existing mirrored site, and resume interrupted downloads.
