Epub export css buglets

Epub export css buglets

A couple of small issues with the css for epub output.

First, back-exp.lua creates, in \jobname-styles.css

    @namespace context url('%namespace%') ;

This should probably be:

    @namespace context url('http://www.pragma-ade.com/context/export') ;

That file also has:

    document,
    %namespace%div.document {
         font-size  : %size% !important ;
         max-width  : %width% !important ;
         text-width : %align% !important ;
         hyphens    : %hyphens% !important ;
    }

which contains the invalid css property text-width. Perhaps that should 
be text-align or text-justify.

Something else appears to be creating, in \jobname-defaults.css:

    pubfld[detail="title"],
    div.pubfld.title {
         display     : inline ;
         font-weight : italic ;
    }

which incorrectly assigns italic to font-weight when of course it  is a 
font-style as far as css is concerned. This can be seen in file 
export-example.css in the distribution.

Here ya go, about as minimal as I can imagine:

    \setupbackend [export=yes]
    \setupexport  []
    \starttext
    !
    \stoptext

and in the resulting export styles directory, I get:

    g:\yoiks-export\styles>grep "namespace\|weight.*italic\|text-width" *.css
    yoiks-defaults.css:@namespace context url('http://www.pragma-ade.com/context/export') ;
    yoiks-defaults.css:     font-weight : italic ;
    yoiks-images.css:@namespace context url('%namespace%') ;
    yoiks-styles.css:@namespace context url('%namespace%') ;
    yoiks-styles.css:    text-width : justify !important ;
    yoiks-templates.css:@namespace context url('%namespace%') ;

So:

  * three unexpanded %namespace%s,
  * one invalid property (text-width),
  * and one incorrect property (font-weight should be font-style).

The *namespace* and *text-width* issues are now fixed, but the 
*font-weight : italic* fault in default.css remains.

I also note that the W3C CSS validator reports for styles.css:

    11     document, div.document     inherited is not a hyphens value :
    inherited

That validator (and others) also report a number of issues for the 
@counter-style rule, which seems to have changed significantly since 
this CSS was developed. Validators report a number of smaller issues as 
well.

I understand that export output is a low-priority feature.
