Patch 2 - Additional genres and French translations

Here are some additional genres alternate mapping.

Looking @londumas' list of genres, I realized that not everybody have their genres set to English.  So I modified popups.xml to provide basic French translation.

Do you think it is the place to do it?
Also, does it support unicode?  For the "e" with an accent, I tried to input  & e a c u t e ; like you have done on R and B, but that did not work.

EDIT:  Please correct the world "accoustique" (should be "accoustic"  in the alternate English section and lower case the "H" on "House".
