Optional UNITY_EXCLUDE_SETJMP_H, different control flow

This reverts commit ee382194.
Removing these changes per coding standard, after the code review

Quell warnings about pointer to integer cast

Fix bug in DOUBLES_EQUAL in unity_fixture.h

With a wider integer width than a pointer, gcc can still warn
when you cast a pointer. Strange but true. To see these warnings
compile with gcc -m32, 32-bit target, and enable UNITY_SUPPORT_64

Using this option changes the control flow of Unity, but is useful on
constrained embedded systems. You can't fully simulate the power of
'longjmp' with just 'return', but Unity still works well, all tests pass.

Move longjump inside caller, to functions returning 'void'
This single function needed to change to allow optional setjmp.h

The setjmp calls are all in TEST_PROTECT() already

Fixture - Remove duplicate output of test name in verbose mode

Organize Makefile so clang works on all platforms, warnings are set

Remove promotion warnings on float constants, Inline the isneg/ispos macros

Always run the tearDown() even if test is ignored

Cleanup floating point print testing, update docs

Rename UNITY_SKIP_EXECUTION to RETURN_IF_FAIL_OR_IGNORE

Thanks for the walkthrough (and all the original work!). Your logic seems solid to me. :)

Defensive coding

Originated from commit c6dc96f3 but are rarely used and not in math.h
Removes float to double promotion warning and simplifies the code
'gcc -std=gnu99 -Wdouble-promotion' spits out these warnings

Delete warning flags included by -Wall, -Wextra, or produce false postives

Remove UNITY_FIXTURES option, which was probably not doing what was
originally indended. It was suppressing the test name even in quiet mode.

Fixture - Ability to set size of pointer list

Fix test that failed when any other test failed

The old type was really just used as a cast-to-int to do pointer math
in char size.

Unity prints float (and double) by default

Fix new type name conflicts

Module generator finishes for partially existing files

This resolves #219. When generating a new module, if all the files to
generate already exist then it fails as before. If some of the files
already exist, then the files that need to be created are created. Any
existing files are not changed.

Also added a bunch of tests for this feature via rspec. Run them from
the test folder with `rake spec`.

Revised internal type naming scheme to better sandbox Unity away from everything else. Sure, short was nice, but not at the expense of naming collisions.
