If a profile has a data files directory that looks like this:
```
files/platforms/one/data.json
files/platforms/two/data.json
files/platforms/three/data.json
```
... the source reader will return the directories in the list of files but with
nil contents. This causes an issue when Inspec::Profile tries to create a sha256
checksum of the profile contents only to try to cast nil to a string when
building the null-delimited profile contents string.
Files that are empty will have an empty string as its contents, so it's safe to
assume that file entries with nil contents are actually a directory and have no
affect on the profile's checksum. Therefore, this change will eliminate any file
entries in responses from the source readers where the contents are nil.

Currently, if the inspec.yml for a profile is invalid (such as including
an improperly-defined multi-line string), InSpec will throw an exception
from the YAML parser that does not given a clear indication that the
issue was encountered while parsing the inspec.yml file.
This change introduces a better exception message to clue the user into
where the problem actually lies.

This adds a new git fetcher. In doing so, it also refactors how the
fetchers work a bit to better support fetchers that need to resolve
user-provided sources to fully specified sources appropriate for a
lockfile.
