Title: remove usage of Thread.current for fallbacks

Fixes #362. Usage of the `Thread.current` hash causes fallback lookups to fail in some instances (see my [example app](https://github.com/hube/globalize-fallbacks)). This file has two other usages of `Thread.local` that may need to be reviewed but I chose not to remove them in order to make the minimum change necessary to address this issue.
