GreenHopper does not work with Turkish JVM locale

GreenHopper creates internally used custom fields if required, storing the field ID to check for existence. Custom field IDs are prefixed with "customfield_". GreenHopper uses uppercase comparison, but under a Turkish locale the lowercase 'i' will not convert into uppercase 'I'.

The result is an exception on every page in GreenHopper, since the custom field for Release Version History can't be found. Additionally, the custom field will be created over and over again, since GreenHopper believes it not to be there.
