Trailing commas in settings.json

[zingmane]

Saving profile runs on error if the config has trailing commas any where in the settings.json.
The error message was also very shortened, so I had to look a while to find the issue.
Unfortunately the JSON specification does not allow a trailing commas, but code has no problem with it, so I think the profile switscher shouldn't either.

This is the snippet that caused the error.

"files.exclude": { "**/.git": true, },

Hmm, I use the same parser that Code itself uses to read the JSON in so I'm surprised that this results in an error.

Fixed in release 0.3.1
