Big update, various things

- Added fir tree and its log, textures from my old Forest mod
- Moved pine tree to hot regions and with a different shape (Pinus Pinea)
- Renamed mod (biomes -> 30biomes)

 ## Data structure
 The properties of each biome are stored in `biomes.csv`. You would find it awfully unreadable if you open it with a text editor. Actually you should open it with a spreadsheet software like Calc or Excel. To modify it, simply modify the cells and save the file with the same format.
