Fix vercmp and add additional tests

This vercmp issue has been a sticking point but this should resolve many of
the issues that have come up. Only a few minor code changes were necessary
to get the behavior we desired, and this version appears to beat any other
vercmp rendition on a few more cases added in this commit.

This commit passes all 58 vercmp tests currently out there. Other 'fixes'
still fail on a few tests, namely these ones:

test: ver1: 1.5.a ver2: 1.5 ret: -1 expected: 1
  ==> FAILURE
test: ver1: 1.5 ver2: 1.5.a ret: 1 expected: -1
  ==> FAILURE
test: ver1: 1.5-1 ver2: 1.5.b ret: 1 expected: -1
  ==> FAILURE
test: ver1: 1.5.b ver2: 1.5-1 ret: -1 expected: 1
  ==> FAILURE
4 of 58 tests failed
