Depth level support.

[JDBS]

I have a big project where i need to import some files with some extensions. Something like that:

-src
* DirA
  * DirAA
    * FileToGet.ext
  * DirBB
    *  AlotOfFilesAndDirectoriesThatIDontWantToLoad (such as node_modules)
* DirB
  *DirBB
....

So, when i do require.ensure('./src', true, /ext$/) it gets the right file. The problem is that it becomes too slow because this require is maping all folders structures.

However you can set false if you dont want to look in subdirectories, but i need to search inside level 1 subdirectories. ¿Maybe could be 2nd parameter a number indicating depth instead of a boolean?. 0 stills being false and other numbers still being true.
