* throw exception if a file cannot be opened * Add a new function in utils.hpp: open_file_or_throw: This function returns an opened std::ifstream or throws by calling `inja_throw`. * Use this function in Parser::load_file which previously returned an empty string if the file couldn't be opened. * Use this function in Environment::load_json which previously threw a `nlohmann::detail::parse_error` if the file couldn't be opened. * In Parser::parse_statement: When including files through `include`, do not attempt to (re-)parse templates from files that were already included. Additionally, this prevents inja from attempting to load in-memory templates by their name from disk. * Add tests that check if an exception is thrown when attempting to open files that do not exist. * cmake: enable C++11 * cmake: require C++11 when depending on single_inja * code style
