new StockTicker module using StockAPI

This is a bit of a work in progress; but this initial version is functional.

We needed a StockTicker (scrolling stock output) for a site we were doing. I found stockapi and the stock module. With a patch stockapi seemed to work but stock didn't and didn't look like it had a std ticker output format.

I whipped up the following module which uses the jStockTicker library and the StockAPI module. The formatting is not correct yet as the output is supposed to be a black background with multiple lines (which you can briefly see on initial page load). Should have that fixed by tomorrow and then may post this as an official project.
