Add script to update libgit2
A call to ".\UpdateLibgit2ToSha.ps1 deadbeef" will: - Fetch libgit2 - Checkout the sha, if it exists as a commit - Build 32- and 64-bit variants of the library, and copy them to NativeBinaries - Update the libgit2_sha.txt file

.SYNOPSIS
3+
Builds a version of libgit2 and copies it to Lib/NativeBinaries.
4+
.PARAMETER sha
5+
Desired libgit2 version. This is run through `git rev-parse`, so branch names are okay too.
6+
.PARAMETER vs
7+
Version of Visual Studio project files to generate. Cmake supports "10" (default) and "11".
8+
.PARAMETER test
9+
If set, run the libgit2 tests on the desired version.
10+
.PARAMETER debug
11+
If set, build the "Debug" configuration of libgit2, rather than "RelWithDebInfo" (default).
