JSON schema for .vscode/launch.json files.

The main motivation behind this is to get code completion and documentation (hover) when using the vscode-json-languageserver while editing debug configurations in an editor that is not vscode and doesn't have debug adapter specific vscode-extensions installed.

Add a $schema line to your .vscode/launch.json file:

{
   "$schema": "https://raw.githubusercontent.com/mfussenegger/dapconfig-schema/master/dapconfig-schema.json",
   "version": "0.2.0",
   "configurations": [
   ]
}

Ensure vscode-json-language is running and you should get property completion, hover/documentation and validation.

PRs that extend the schema with properties for more debug adapters are welcome
