Beamer enumerations

[Jean-Pierre Chrétien]

Dear developers

I had a question on the French list about the following problem : with Beamer, 
enumerated subitems are numbered alike main items:

1 item
2 item
   1 subitem
   2 subitem
3 item

The solution is to add a command in the preamble to redefine subitem numbering 
style. I added it to the wiki :
