Update package.json for VS Code 0.10.7

There have been some changes in how extension code must get new versions
of the vscode.d.ts file which contains VS Code API type definitions.  This
change updates the package.json file so that a new installation script
is used to pull the appropriate version of the vscode.d.ts file.
