Branch mining turtle

So I wrote my first branch mining script,
It works perfect, also when it encounters gravel / sand, but where and how could I make the code even better / shorter?

Thanks :)/>

I'm not sure if people would approve of asking "what can I do" questions, but anyway:

1. Fix your indentation. Line 6 really threw me off until I realised it was a statement, not a function.
2. Modify lines 11 to 15 so that it doesn't dig in all 3 directions whenever there's something in only one of them.
3. Not a big deal, but most code is written in English.
4. I'm not sure what lines 30+ are supposed to do (mine in some crazy hard-coded order?) but I reckon a for/while loop would work better.
