Finalize the first working implementation of the testing framework (100%)

crux-macro:

• Implement support for basic Ignore/Should_panic
• Add skeleton code for further improvement using proper attributes

crux-runner:

• Add support for printing any "normal" output when a panic occure (showing status of the running test, printing summary, etc.)
• Properly marking every tests remaining as skipped during a panic
• Try to improve optimization using likely/unlikely intrinsec for panic
• Diminue the unsafe overall interface size by using smaller block
• Fix the bad skipped display within the summary
• Add some sanity check just to avoid unwrap without testing
• If the code still find itself in an unexpected environment it will call for a hard crash

known issue:

• reason aren't displayed for FAIL/ABORT test (Option is none)
