Home page: displays only main (non-f) block elements, and shows their traditional group numbers.

Problem: /group/3 shows the 1-32 group 3 (La and Ac), not the traditional group 3 (Sc, Y, Lu, Lr).
Solution: make the f groups have pages named /group/f1 through /group/f14. On (main) group pages, if group number is greater than @main_pauses_group, for database purposes use group number +14 (but still display traditional group number).
