negate config flags and comment them out by default; this allows command-line preprocessor symbol injection to control flags. Useful for having a master copy of utpp that build with different flags for different compilers/platforms
fixed bug where tests weren't correctly executing while testing the TestRunner (accessing the Details and Results singletons was redirecting failures to bogus RecordingReporters, instead of the real UT++ test engine). Hoisted assert failure reporting into ReportAssert, in preparation for setjmp/longjmp assert handling in the absence of exceptions. Slight renamings and cosmetic fixups
