The version of leveldown is too old for FreeBSD

[dper]

It seems that leveldown is too old to work with FreeBSD. The version right now is, as specified in package.json, ~0.5.0. Support for FreeBSD was added to leveldown in 0.8.2. The relevant code is a line in https://github.com/rvagg/node-leveldown/blob/0.8.2/deps/snappy/snappy.gyp.

 , ['OS=="freebsd"', {'os_include': 'freebsd'}]

In version ~0.5.0, an attempt to install databank-leveldb errors out.

I have not tested anything and don't know whether moving to a new version would introduce other bugs.
