SharpReader 0.9.7.0

- Run internal browser in restricted security zone in order to make IE responsible for blocking restricted content, instead of just doing so by parsing and stripping tags.
- Allow embedded CSS styles in item descriptions (was previously disabled because of javascript exploits that are now caught because of the security zone).
- Support both as well as as there was some confusion as to the proper capitalization of this element.
- Fixed linebreak handling for some feeds.
- Improved handling of relative urls in atom feeds.
- Now displaying enclosure links at the bottom of the item description.
- Fixed installer to no longer complain if only .NET 2.0 is installed.
