    add .gitignore; support for building on a few BSD variants

…location

Just patch Control.Monad.Trans.Resource to export some types and implement
runResourceT as runLevelDB with custom alloc/dealloc strategy. Removes the
re-export of teh whole Resource module.

* fixes #5
* Todo:
  * tweak foreign imports, possibly not all of them need to be 'safe'
  * maybe it's time to switch to record syntax for options to reduce clutter

Interestingly, this fixes segfaults with custom comparators.
