GitButler Integration Commit

This is an integration commit for the virtual branches that GitButler is tracking.

Due to GitButler managing multiple virtual branches, you cannot switch back and
forth between git branches and virtual branches easily. 

If you switch to another branch, GitButler will need to be reinitialized.
If you commit on this branch, GitButler will throw it away.

Here are the branches that are currently applied:
 - Virtual branch (refs/gitbutler/Virtual-branch)
   branch head: 8d7d2c1e2b6e5d073c2e9eab95af2b7ce027a6f0
   - Gemfile.lock
   - rubytree.gemspec

Your previous branch was: refs/heads/master

The sha for that commit was: c9653ba
