Development mode crashes the server repeatedly about vscode-htmlhint

[mike-kaufman]

IIRC, to debug the "server", you need to:

1. open one vs code instance on htmlhint (code ./htmlhint), and a second vs code instance in htmlhint-server (code ./htmlhint-server)
2. build & "install" the server: on command-line npm run compile in htmlhint-server directory
3. build the extension: on command-line, npm run compile in htmlhint directory
4. launch a debug instance with the extenion active: from the "htmlhint" vs code instance, launch the "Launch Extension" debug confugration
5. Attach to the the htmlhint-server: From the htmlhint-server vs code instance, launch the "Attach" debug configuration
