Option to edit organisation from project or software organisation pages

[dmijatovic]

In the codebase there is a legacy code that shows the edit organisation button in the list of organisation. This feature should be removed because the organisation settings are extended over the time and a simple edit organisation modal does not cover all the settings.

We do provide a link to organisation page and if the user is administrator of the organisation it will be able to see settings tab and change any of organisation settings.
