Configure Project icon

The "configure project" page on the projects mode has currently only a temporary icon and thus needs one.

Opening Projects in Qt Creator 2.5 leaves the project in a state where they are not yet configured for building and the user is shown a page in the projects where the user can configure the project. See the attached screenshot "configureproject.png" of the page.

For reference, after hitting configure there are two pages for those settings, see the screenshots configureproject1.png and configureproject2.png

Ideally the icon would match the style of the build and run icons and indicate either the action of configuring the project, a pencil or checkmark list might work; or indicate that the page is for the same build and run settings shown in the configureproject1.png and confgiureproject2.png by maybe showing a mixture of both icons.
