Fixed issue #47: when deleting an item via deleteItem, current selection is maintained.
Deleted garbage
Fixed unclosed table element in the tooltip. (see issue #58)
Added JSON date parsing

Some rudimentary support for parsing JSON dates - accepts Date object
(just returns), stupid .NET serialisation format (e.g
/Date(2584358098+0500)/ ) or any parsable date using "new Date(date)".
Possibly not the most efficient, but works.
parseJSONDate

Attempts to parse dates when adding objects. Accepts Date, Stupid
ASP.Json Dates and anything else that is parseable by Date.Parse
