HTML element is depreciated or obsolete

[StephDriver]

some pages still use html font tag instead of CSS.

This is likely due to copy/pasting of text from a word processor which then specified all the styles.

example

<font face="Times New Roman, serif">
<span style="font-size: 14.6667px;">  </span>
</font>

this should be fixed in the new bleachfield work, going forward, but it runs on the 'save' function, so when this new feature is added we need to run it across all previously saved text that it will now apply to (e.g. article titles, abstracts).
