some encoded HTML entities not displayed properly

[saumier]

Some event titles and descriptions are not displayed properly because they still have encoded HTML entities. HTML entities are frequently used to display reserved characters (which would otherwise be interpreted as HTML code).

It appears that strings are encoded twice when they should only be encoded once. More investigation is needed.

I've fixed the issue and now ampersands are no longer double-encoded - will monitor to ensure no ill effects from this change, but looks like it was only the event titles that needed adjustment...

Also, description has been fixed (same issue with double-encoded ampersands)
