Grab file hashes from browser extensions

[jjsendor]

So far OSXCollector can list all extensions from Firefox and Chrome but information about a particular extension is limited only to the information available there (name, install date, update page, etc.).

Getting file hashes from all of the extensions installed on a machine would provide a better insight when investigating whether a malicious extension is installed on the machine.

Firefox and Chrome use standard directories where the extensions are installed so it won't be a problem to get the file hashes from there.
