Create snippet from selection

Similar to Snippets View

Not very important. There are might be extensions that do it better (write to file automatically instead of just giving an escaped json)

Good idea. Let's keep this open for our wish list. Some ideas for how to go about it:

We can create or add to [language].json snippets in your workspace by default using active editor language id and code block selection.

Then on workspace or project scoped snippet files already loaded in #46, we can add snippet file context menu to move those snippets to [language].json snippets def. in User/snippets to promote them for global user snippets setup. Similarly we can add that option for project scoped snippet tree item.

def. will need to add this feature to be able to create vscode ext. snippets from good extensions for https://github.com/RandomFractals/vscode-extension-snippets/issues/5
