Joomla backend - font size is too small be be readable

Modify joomla.css so that the base font size for table rows is 1 em - per suggestions in this forum thread:
http://forum.civicrm.org/index.php/topic,2161.0/topicseen.html

There may be other changes needed - but for now, just over-riding the .95em font-size for table rows, help block and "description" blocks from civicrm.css with these directives:

#crm-container table tr {
font-size: 1em;
}

#crm-container div.description, #crm-container span.description, #crm-container dd.description {
font-size: 1em;
}

#help {
font-size: 1em;
