[thejustinwalsh]

• Updated syntax highlighting scopes
• Support single quote strings
• Proper nested object detection

Example from vscode-pbtxt repo: https://raw.githubusercontent.com/thesofakillers/vscode-pbtxt/master/.vscode-test/test.pbtxt

Here is an example that totally destroys my key-value matcher. Looks like you can concatenate strings as a value of a key, not sure off the top of my head how to capture this? Maybe a string value to a key needs a begin and end with allows patterns inside?

The changes look good - anything else needed for this PR? I'd recommend trying a feature where we generate from YAML in a similar vein as the official vscode extensions. That process may offer a bit of clarity to help handle those funky edges, as well as open up another testing pipeline. I'm happy to get the ball rolling and get you a draft PR.

Would love to see this. Just to be sure I understand.
