We have the SparseVerb from VFS for Git. Update it to be a small layer over git sparse-checkout add with an additional scalar prefetch --folders-list first. That prefetch, along with #62, will make the expansion much faster.

Merge pull request #54: Initial sparse implementation
19d745f 
Uses the code currently at microsoft/git#180. Covers the basics of #8.

* The default `scalar clone` runs `git sparse-checkout init` so the working directory only has files at root.

* Run `git sparse-checkout add <folders.txt` to pipe in a list of folders, and it will expand those files.

Example workflow:

```sh
$ scalar clone https://dev.azure.com/gvfs/ci/_git/ForTests
Clone parameters:
  Repo URL:     https://dev.azure.com/gvfs/ci/_git/ForTests
  Branch:       Default
  Cache Server: Default
  Local Cache:  C:\.scalarCache
  Destination:  C:\_git\test2\ForTests
Authenticating...Succeeded
Querying remote for config...Succeeded
Using cache server: None (https://dev.azure.com/gvfs/ci/_git/ForTests)

WARNING: Unable to validate your Scalar version

I spun up a few remaining issues for follow-up work: #76, #77, #78.
