Better integration between applications and projects and merging communications

[frjo]

They feel separate today in the UI.

1. One suggestion is to create tabs to navigate between them like this:

Have renamed "Submission details" to "Applications" as a suggestion as well.

2. The second part is unifying/merging the communications for application and projects in to one single view. Each comment would have a marker in the db telling if it was made in the application or the project face. This is so permission can be managed for all groups.

3. Should the status bar above application/projects always show the project statuses when a project exist?
