- move getProjectsWithLabelCounts to IDF_Views (where the other functions

reside as well) and make it static
- refactor out the code from getProjects that determines which projects
  are visible by a user and use the same code to restrict the count that
  we calculate for all available project tags
- calculating the project stats is now no longer O(5n) but simply O(5)
  when it comes to SQL queries (where n is the number of filtered projects);
  remove the member statistic since it makes no sense in this context
