JIRA code formatting renderers

It's a good idea to enable a renderers in JIRA to improve the look of bug reports.

We has discussed this feature with David and realized that it shoud be done by sourcefabric admins.

Here're some info about the renderers and what they will give us:

 - the renderers overview with screenshots and how to configure them
http://confluence.atlassian.com/display/JIRA/Configuring+Renderers#ConfiguringRenderers-ConfiguringRenderers

 - wiki markup language for wiki renderer - very nice capabilities!
http://jira.atlassian.com/secure/WikiRendererHelpAction.jspa?section=all

- editing rich text fields
http://confluence.atlassian.com/display/JIRA/Editing+Rich-Text+Fields

So, JIRA have a lot of nice features we are missing now. The only thing we need is to enable them.

Please take a look at the first link and post the list of renderers/extensions you would like to have enabled.
