fix Bold and Italic in Safari+discussion

this is a duplicate of make bold and italic work in safari.  I'll close that one.

I changed it to "moderate" from "easy", because I don't think we're ok to turn off that filter.  That will mean any old pasted style will make it through, which not only allows for ugly formatting from other sites, which is a real pita to fix, but also makes some very strange things happen when text is pasted from within wagn and in the process lots of important wagn formatting gets moved from class to style.

Notify Andy at ICAH when there is progress. (Ethan from duplicate ticket)
