test/RunTests: add -R<r> for ratio epsilon support + add ratio-epsilon fuzzy match when abs(Num) >= 1.0 and delta-epsilon fails
Merge branch 'master' of git://github.com/JohnLangford/vowpal_wabbit
test/RunTests: oops, merged recent windows specific changes as well
test/RunTests: oops, restore cygwin diff/cat/touch
test/RunTests: switched 'touch' to perl internal implementation +
somewhat cleaner and more general Windows/cygwin external command (diff/cat) handling
test/RunTests: support optional alternate reference files (suffix: -mswin) under windows
test/RunTests: add documentation for windows '-mswin' suffix reference-file convention
test/RunTests: simplify: only one -E (epsilon) needed + Clean-up windows
support, setting the path correctly should be sufficient in cygwin
