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

Conflicts:
	src/unity.c
	src/unity_internals.h

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.

Fixed error when path provided in module name.

- configurable case.
- better passing of includes and boilerplate information
- test only pattern
- optional naming conventions for case

Takes about 10 minutes to run all floats, so split into 3 tests for parallel
running later. This was useful during development for finding hard corner cases
and getting the routine to high quality. Off by default.
Note that all floats 16.0 and up can be represented uniquely (in this format) and will
round-trip back to the exact same float with sscanf(). This property is true for
UnityPrintFloat, despite a few rounding error cases, it will produce output identity.

Better comments and refactor on round ties to even
Add upper threshold value on round to even feature since numerical precision issues
start to give approximations when dividing one large double by another. When tested
on float values, using 1e22 gave the fewest rounding errors.

Fix warnings from gcc. Some float constants do not behave well in existing tests.
Add casts where conversions could be imprecise.

Move double tests down in the file

Remove UNITY_FLOAT_VERBOSE entirely, add option UNITY_EXCLUDE_FLOAT_PRINT
Remove some questionable float casts from doubles
Default to Round Ties to Even behavior, add option to Round Ties Away from Zero

Linux gcc & clang and OSX clang produce output with ties round to even
Windows mingw gcc does not
Example 0.0078125 prints '0.007812'
