update aromaticity to require unsaturation at single-atom donors
test the above two things
This is not necessarily completely stable, but all current tests pass
(once obvious changes have been made). We will just have to see where
the aromaticity changes cause trouble going forward.
Conformer.cpp: make sure we don't ask for space for zero atoms.
Kekulize.cpp: don't complain about marked bonds if we aren't removing markers.
molopstest.cpp: bad smiles corrected in one test.exe
ROMol.cpp, RWMol.cpp: extra preconditions added (should have been there all along)
Wrap/MolOps.cpp: docs for replacesubstructs.
- Remove requirement that boost be in $RDBASE/External on windows (the BOOSTHOME environment variable is now required)
- fix dependencies
This builds on windows in debug mode now and most tests pass. There's a problem with PySVD in debug mode and for some reason the rdAlignments wrapper test fails; but these don't seem super important.
