More distinctive project name in project selector / #4785

We have same projects for different companies, let's say a project named "documentation". So the projet selector shows a number of "documentation" projects. We worked this around by adding the company short name in the project name. Works fine - but we have to type in data which is already in the database. I guess streber could do it itself with little changes in code (and optionally controlling this behaviour by setting a customization parameter yes/no).
