#4926: .nav inline-block fix for IE7
#4926: .nav inline-block fix for IE7

There's a way to force IE7 to apply inline-block display on
elements that were not originally inline.

See http://foohack.com/2007/11/cross-browser-support-for-inline-block-styling/
for more details.

Hack suggested by Leho Kraav, many thanks!
