Add more exceptions on pluralization for -fe/-ve endings

[phstc]

I'm not sure what's the best way to deal with these pluralization exceptions - if adding in the Rails core or only in the applications, but currently without this commit 'olive'.pluralize => 'olifes' instead of 'olives'.

I tried to update the plural/singular regular expressions that match 'olive', but I got some conflicts with 'knife', 'wife', 'life' etc.

• wi_fe_ => wi_ves_
• sa_fe_ => sa_fes_

• wi_ves_ => wi_fe_
• oli_ves_ => oli_ve_

Thanks, but inflections are frozen, to avoid breaking existing applications; please just add what you need in your application. We added a comment at the top of the file a couple of months ago (07c7024), but it looks like your branch predates it.
