Extensionless "typings" entries in package.json no longer work as of TypeScript 2.1.0-dev.20160820

[rbuckton]

A recent change in TypeScript has caused a breaking change that affects the vscode-languageserver, vscode-languageserver-types, vscode-languageclient and vscode-jsonrpc packages. Specifically, extensions are now required in the "typings" field in package.json. These packages all have something like the following in their package.json files:

"typings": "lib/main"

Due to this change, all of these references must instead now point to something like the following:

"typings": "lib/main.d.ts"

TS should not be breaking this scenario. @andy-ms can you take a look at the original change.
