Make timechart series comparisons case insensitive

[mstemm]

Got my friend to try out the stock prices example program. Initial impression was that he tried to use 'close' in the series filter to just select the close price, but since it didn't match 'Close' it didn't work. Maybe the series filter match should be case insensitive?

Thoughts: either yes make the matching case insensitive, or have autocomplete in the series filter and make that case insensitive i.e. substitute your "closing" for "Closing" in the filter box, so it's a bit more explicit.
