Updated fishing mod from Xanthin fork

- I found recently that MossManikin's fishing mod is outdated: its last commit has been sent on August 2013. However, there are some forks of it. The mod updated is Xanthin's one. It updates API, and a little bit of global variables.
- Variables specifically modified for MFF have been changed to their last state.
- The fork works perfectly fine for 0.4.11-dev
- It can use intllib for translation
