Added "const" to one argv parameter that was missed when adding strict error checks. (thanks, trianglee!)

Move announceTestRun() after UnityBegin()

undef defined callc/realloc macros

Make Unity's compilation flags stricter

Primarily -
* Added "static" to static functions.
* Added proper signature with "void" to functions without arguments.
* Marked unused arguments with "(void)".
* Removed entirely unused static functions.
* Added "const" to preserve const-correctness.
* Added function prototypes for external functions.

New macros for controlling use of weak linkage (Thanks Zane!)

 - `UNITY_WEAK_ATTRIBUTE`, if defined, is placed before declarations of weakly
   linked symbols. If not manually defined, it will be automatically set to
   `__attribute__((weak))` on GCC and Clang, except for Clang for Win32.
 - `UNITY_WEAK_PRAGMA`, if defined, will cause preprocessor to emit
   `#pragma weak setUp`, etc. Ignored if `UNITY_WEAK_ATTRIBUTE` is defined.
 - `UNITY_NO_WEAK` undefines both of the above resulting in no weakly
   linked symbols.

Work around for ThrowTheSwitch/Unity#93

Warning fixes (thanks kotofos!)

no arguments for UnityPointer_Init (thanks Kotofos) 

Print newline after each test, but not before (Thanks Zane)

This change makes parsing the results easier for tools like ceedling,
which was choking when a test used stdout and there wasn't an
EOL after "PASS" (ThrowTheSwitch/Ceedling#41).

Declare local variables before UNITY_SKIP_EXECUTION.

Fixed -Wcast-qual gcc warnings

But they look a bit different.

warning: cast discards ‘__attribute__((const))’ qualifier from pointer target type [-Wcast-qual]
FYI, "-Wcast-qual" is not a default option.
The main idea: If some function receives "const void*"
why should it operate with "void*" (or something) afterwards (after casting)?

Fixed script unit tests. Fixed generate_test_runner configuration loadin...
(Thanks Mark McCrum. You are awesome!)

Awesome. Thanks so much!

- Modified rakefile to look in correct directory for script unit tests
- Updated paths in script unit tests
- Updated 'expectdata' files to match latest version of generated code
- Fixed bug which prevented generate_test_runner from loading config from
yaml file.

reworked character strings to be an array type so that storage classes are handled better for picky compilers.

- made help more clear
- added ability to rename setUp / tearDown / and test prefix.
