The user can specify UNITY_OUTPUT_CHAR_HEADER_DECLARATION and
UNITY_OUTPUT_FLUSH_HEADER_DECLARATION when he would like to declare
UNITY_OUTPUT_CHAT or UNITY_OUTPUT_FLUSH respectivly

- Fixed some style issues.

Fixed UNITY_TEST_ASSERT_EACH_EQUAL_*

Fixed copy-paste error for:
- UNITY_TEST_ASSERT_EACH_EQUAL_INT64
- UNITY_TEST_ASSERT_EACH_EQUAL_UINT64
- UNITY_TEST_ASSERT_EACH_EQUAL_HEX64

So that the comparison is done on the expected _value_ instead of the _array_.

Started to flesh out rubocop settings for this project. Added rakefile tasks to do so. Updated first script to make it compliant.

Turn UNITY_OUTPUT_FLUSH off by default. Added a quick-define for the most common case: UNITY_USE_FLUSH_STDOUT. Clarified documentation. Fixes issue #269
