[GitTool] Adding a directory with a large number of files to a repo causes a long delay when inspecting the repo in GT Git Tool

[JupiterJones]

To recreate:

1. add a directory with a bunch of files - in my test case it was around 1500 files, largely c++ source.
2. click on, or refresh, the repo in the GT Git Tool.
3. wait for the inspector

Does it take a while for the tool to reload or is all of GT unresponsive?

[JupiterJones]

GT is unresponsive

Working with Git is at the moment synchronous. When we will move to CLI, we will have better responsiveness.
