New module: Stock API

The Stock API module  has been released to the public. This module was developed by Matt Westgate for the wonderful BuyBlue web site.The idea is that this module will fetch the stock data over the internet only when needed, and caches the info in a database table, hence network lag does not slow down the user response, and the system does not get bogged down if too many page views with stock data in them. Since Matt is busy with  E-Commerce, and other stuff, he asked that I take over this module. Of course, this is a good idea, since I do not want code duplication with my original stock module.So, I modified my stock module to use the Stock API module, hence centralizing the source of the info. This is much cleaner than having fragmented modules with overlapping functionality.
