Added ability to inject defines, much like what was built into Ceedling before Ceedling switched to just using this generator.

This fixes #220.

Removing strings from test files is still dangerous, but much
less likely to cause problems after this change to do the
removal after removing comments.

The bug could still manifest if a test file contains defines two
macros, one that contains a single quotation mark and then another
defined somewhere after it that contains a single quotation mark.
Everything in between the aforementioned quotation marks would
still be ignored after this commit, but that is an unlikely
scenario.

Updated method of testing generate_test_runner script to be a FUNCTIONAL test instead of a perfect code match. Backfilled most tests and added some coverage not previously present. Still need to test new command line args and a few cmock details.

Script verification hasn't been added yet.

feedback from @mvandervoord (Thanks).

This supports mock headers of the form:
    #include "some/dir/MockMyCode.h"
Where the mock name is actually MockMyCode.

I *think* this is the most common scenario when working with mocks
in subdirectories but if not this could be modified to support
alternate schemes.

Changed the guard syntax as it was cumbersome for header files in deep
sub-directories. Added framework/mock includes to make the header file
stand alone. Made sure that a valid prototype was generated in the case of
no arguments (void).

This allows alternative entry points. This is intended for the
integration of the unit test into a larger system or for it to be used with
a platform/OS which requires an application entry point other than main. At
the moment there is no way to change the type signature.

- Fixed a big ugly error in the fancy RUN_TEST handler

Output used headers from test runner generator

the test runner generator now has the ability to also output a header file for the tests, which can get pulled into the test itself if desired.

protect against capturing both declaration and definitions and therefore creating a runner which runs that test twice.

Added break out of system vs local includes for enhanced include-based dependency extraction to aid new cmock Make task/build generation.
Bumber build and version info since new external capability added for querying includes.

Added type_sanitizer.rb to consolidate converting a string to a valid C identifier, which will allow CMock and Ceedling to use the same construct which is currently duplicated in each repo.

- 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.

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

support tests named spec as well.
clean up UnityBegin to make us not have to dig inside it to inject the filename.
Add UNITY_OUTPUT_START() and UNITY_OUTPUT_COMPLETE() for future use.

Added more robust handling of test includes, and to provide backwards API compatibility for Ceedling

There was no reason that CMock init and destroy calls should be in the protected blocks. teardown is more flexible if verify is called afterwards.
