(GH-116) Fix packaging to conform with vsce workflow

Previously the gulp file could be used to package the extension however that is
not how the VS Code Extension tool workflow operates (vsce).  This commit
changes the tool chain so that vsce calls the gulpfile during pre-publish to
ensure the language server is updated prior to packaging.
