[development] Conditionally include include files

[Gabor Hojtsy]

Locale module is a very easy target there, since it already includes 
most of its code from locale.inc, and it has a custom menu callback 
which dates back to the time before this patch landed. It should be easy 
for someone to pick up and update to this new functionality!
