Spell Check; Better handling of HTML and other tags

When using the Spell Check button and displaying the "Spelling" dialog, text (or part of) that may have been HTML or tags would be spell checked, e.g.:

•  
• * [BranchId] This was especially apparent when spell checking an email that had been entered as HTML. The "Spelling" dialog will now ignore the following: * Anything with "&" and ";", e.g., &nbsp; * Anything that looks like an HTML or XML tag, e.g., "<div>" or "
  "
• Anyting that looks like a special tag, e.g., "[ClientId]"

NOTE: The wiggly red line that appears beneath words may still appear in certain circustances, e.g., for a "[ClientId]" tag.
