Add logic to grab the delta of binaries if there are changes in the installed packages
Fix for https://github.com/scriptcs/scriptcs/issues/2
Fixes #296 - Assembly reference missing with ..

* Wrote unit test to prove failing path resolution
* Implemented change suggested by @khellang (Use `GetFullPath`)
Refs #296 - Ensure that the method returns a directory path

Ensure that the method returns a directory path and not a file path.

Requires that the path have a trailing slash to indicate that it is a
directory. Not really sure how to avoid this?
Using correct assertion library and returning the correct path if the path is a filename or directory. Would prefer if it was all in memory, but unsure as to how it should be designed.
Update ServiceStack.Text from 3.9.44 to 3.9.47
ScriptCs and ScriptCs.Core should reference ServiceStack.Text v3.9.47 instead of v3.9.44
