Make #underscore reversible

Hello All,
  I've submitted a patch ( to
enable #underscore to be reversible.

  I had trouble creating a class named "CRSContact", and it turns out
that underscore and camelize are not reversible in cases where there
are 3 or more capital letters. As there is a dependency between class
name and file name I think it would be beneficial for underscore to be
reversible, however this would change the existing behavior of how it
handles acronyms.

The standard approach to acronyms in class names is to capitalize only
the first letter, e.g., CrsContact. The underscore/camelize process is
then perfectly reversible.

I ran into this same situation and just went with the Rails flow.
Aesthetically the class name is not ideal, but the underscore
crs_contact is certainly nicer than c_r_s_contact. Given that
hundreds of apps probably rely on this behaviour it seems like a bad
idea to change it.
