Added bundler as default gems. Revisit [Feature #12733]

  * bin/*, lib/bundler/*, lib/bundler.rb, spec/bundler, man/*:
    Merge from latest stable branch of bundler/bundler repository and
    added workaround patches. I will backport them into upstream.
  * common.mk, defs/gmake.mk: Added `test-bundler` task for test suite
    of bundler.
  * tool/sync_default_gems.rb: Added sync task for bundler.

+class Bundler::Thor
+  module Actions
+    # Creates an empty directory.
+    #
+    # ==== Parameters
+    # destination<String>:: the relative path to the destination root.
+    # config<Hash>:: give :verbose => false to not log the status.
+    #
+    # ==== Examples
+    #
+    #   empty_directory "doc"
+    #
+    def empty_directory(destination, config = {})

+    # other actions like create_file and directory.

+    # This implementation is based in Templater actions, created by Jonas Nicklas
+    # and Michael S. Klishin under MIT LICENSE.
