Branch and pull requests improvements for Visual Studio

This post introduces enhancements to the Git experience in Visual Studio 2015 Update 1. Key improvements include: 1. A new status bar in VS that displays the current repository and branch, and provides quick access to create branches, view branch history, and manage branches. 2. Faster search across local and remote branches, including path segments. 3. A pull requests page in Team Explorer that mirrors the web experience, showing current PRs and those assigned to the team, with links to create new PRs. 4. Simplified viewing and connection to projects that contain both Git and TFVC repositories.
