Update dependencies. (#7)

* Update dependencies.

* Skip 'highest' test; Travis can't run 'composer update' because gd is not installed by default.

* Use new scaffold components too. This means we need to abandon testing on old versions of php.

+# Normally these settings would be done with macro attributes for improved
+# readability and easier maintenance. However macros can only be defined at the
+# repository root directory. Drupal avoids making any assumptions about where it
+# is installed.
+
+# Define text file attributes.
+# - Treat them as text.
+# - Ensure no CRLF line-endings, neither on checkout nor on checkin.
+# - Detect whitespace errors.
+#   - Exposed by default in `git diff --color` on the CLI.
+#   - Validate with `git diff --check`.
+#   - Deny applying with `git apply --whitespace=error-all`.
+#   - Fix automatically with `git apply --whitespace=fix`.
