In themes the colors for content links can be configured separately from the system link color. Currently this does not apply to forum content, wiki content, blog content etc.
It is desired to use the content link color in all user generated content.
For this purpose, a new css class o_user_content_block is added to the code. The idea is to add this class to all user generated content. Using this class it is possible to style content different than the application elements.
