Integrate with Bear

[i-ky]

As mentioned in #4 (comment):

It is an option to "simply" integrate basset with bear as a low-level intercept mechanism, this way all high level functionality (like support for partial builds) will be automatically provided by bear. basset will focus entirely on intercepting the commands. See the relevant discussion.

I think this may be the best way forward. Bear is the leader among compilation database capturing tools, it is packaged for many platforms, it is widely known and feature-rich.
