Portfolio Manager to add/remove stocks. Self + Search should not be add/removable, all others are.

Implementation

• Repurpose Google Gadgets XML format for interchange (handles translations, long term we want to support writing stocks in HTML+js too)
• Create initial versions of XML files for each existing stock
• Replace current listing.xml file with these XML files
• Rework Google Gadgets parser in online-desktop to be reusable module for parsing

• Adapt bigboard internal code (StockReader etc., to use load file:/// urls)

• Create stock viewer which loads all known modules
• Add add/remove links to stocks in stock viewer which changes GConf

I created two mockups for this. First has no descriptions as the existing stocks don't really have a description.

The second contains a short version of the description in the description pane. Some additional details need to be worked out.
