#32 minor css errors in Header_html.inc.php

[Jez Nicholson]

Pretty minor really, but popped up as errors in Firefox.

Header_html.inc.php line 168 has css properties
'margin-width' and 'padding-width'...should these not
be 'margin' and 'padding'?

<td class="navigProjectSectionSeparator"
style="border-left-width: 0; border-top-width: 0;
margin-width: 0; padding-width: 0; text-align: right;"
align="right">

should read:

<td class="navigProjectSectionSeparator"
style="border-left-width: 0; border-top-width: 0;
margin: 0; padding: 0; text-align: right;" align="right">
