To change this within SharePoint:
1) Navigate to C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\Resources
2) Save a copy of SPSCore
3) Change the Values within, to the desired spelling!
You may need to recycle applicaton pools, or do an IISRESET. You may also have to re-create the site.
I do have some jQuery that can also make these changes… I will add that here at a later date.
