Add a filter text box to the ProjectListScreen that allows users to
filter the displayed projects. If a filter string is provided only
projects that contain this string in their name are shown. The project
list is automatically updated while the filter string is typed.
Being able to filter the project list makes it easier for users to
search and find a certain project.
