Bug fixes

Fixes for two crashes:

• Crash trying to post analytics while offline.
• Crash after blaming non-added file in a git repo.

Fix Visual Studio integration

Fixes a bug that would crash the app on startup when launched from Visual Studio's Tools menu.

This release may create a duplicate "GitBlame" External Tool in Visual Studio; you'll have to manually delete the older entry.

Fix "Open"

Fixes multiple issues related to the Open command, including crashing and attempting to open files outside of a git repository.

Add logging

Add basic logging to help diagnose problems in installed versions of the app.

Visual Studio integration

This minor update will prompt you to integrate with Visual Studio at startup. Choosing "Yes" will add a new "External Tool" to the Tools menu.
