Merge #214: vscode: fix icons and .json files

b3f07cd vscode: bump version to 0.3.1 (Volodymyr Herashchenko)
66f22e7 vscode: fix icons and `.json` files (Volodymyr Herashchenko)

Pull request description:

  There is an issue with displaying icons -- `icon-theme.json` counts as a
  separate icon theme, so other icons besides `simf` and `wit` didn't
  displayed.

  Also, I had removed activation of LSP for `.json` files, because it
  works on **all** jsons, which is obviously not desired.
