Show types as variable-2

Visual Studio shows type names (classes, interfaces) with a different color. In this pull request I added this feature: the build-in types (string, number etc) and all identifiers that start with a capital letter (types are written in PascalCase), are shown as variable-2:

(I use a custom theme in brackets)

Also I added grunt-template-jasmine-istanbul to the package.json file.
