Some PML conversions cause FlightCrew errors

[Simon Burge]

Two PML conversions cause FlightCrew error reports.

\w="85%" for a horizontal rule/line causes "Error schema not satisfied : attribute 'width' is not declared for element 'hr' near column 35". This generates :
    <hr width="85%" class="calibre2"/>
If I move the width= bit in to the CSS class then the FlightCrew error is fixed. However if there's more than one length horizontal line I need a separate CSS class for each width.

\X0\cPROLOGUE\c\X0 to create a chapter title with the \c centre tags inside the chapter tags causes "Error schema not satisfied : element 'div' is not allowed for content model '(a|br|span|bdo|map|object|img|svg|tt|i|b|big|small|em|strong|dfn|code|q|samp|kbd|var|cite|abbr|acronym|sub|sup|input|select|textarea|label|button|ins|del|script)' near column 126". This generates :
    <h2 class="calibre3" id="calibre_pb_0"><span id="pml_toc-0" class="calibre4"></span><div class="calibre5">PROLOGUE</div></h2>
If I change the two "span" to "div" it fixes the FlightCrew error. I'm not sure if that is the best fix though! It works for me. :)

Please let me know if you'd rather two separate bug reports for these.

Neither of those errors are meaningful. They will not cause any
rendering issues in any reader. However, since they are easy to fix, I
will do so.

Fixed in branch master. The fix will be in the next release. calibre is usually released every alternate Friday.

Thanks! Yes, I couldn't see anything obviously looking wrong with the epubs on a Kobo. But nice to have the FlightCrew warnings fixed. Appreciate the fast response and quick fix!
