Moved xpath into boostrap java

And removed complex-find while at it.

Submitting to @bootstraponline for review.

I'm working now on changing the getPageSource code to reuse the same code here.
Oh lol. Hi Eric. I was wondering who from the community decided do to such an in-depth review ^.^
I have your user page open in the next tab, but didn't read it yet.

Basically, a lot of the errors you mentioned are things that I would rather just see spectacularly fail, rather than get caught properly. If reading the dump.xml file tosses a permissions error, there's a whole lot more wrong going on than just that command.

Still, better error reporting could be nice.
