Allow HTML content in the Strategy description panel

Hi, 
The <Description> section should be able to contain some special characters or HTML formatting.
I added support for this in SwingStrategyDescriptionPanel.
Also added specific support for &apos; character, since it is apparently not handled as such. (maybe adding a dependency on apache comons lang could help do somthing more generic : http://stackoverflow.com/questions/1265282/recommended-method-for-escaping-html-in-java)

*Question which have nothing to do with the pull request:*

Is there a release process for this project ? Do you recommend users release on their own forked repository ?
