Fixed the incorrect reading of InChI of single heavy atom radicals #3526902. The implicit hydrogens provided from the InChI code are added explicitly to the OBMol, the spinMultiplicity assigned, and the hydrogens removed. Slower, but more systematic.
Modified Windows installer.
The data and examples are now in APPDATA, which is more logical and accessible. File deletion on Uninstall  is much better.
src/depict/asciipainter.cpp: Improve the handling of text labels. Still not fully correct - needs a bit more care to avoid text overwriting other text, e.g. obabel -:NC(CN)N -oascii. Good enough for people to play with in OB2.3.2.
Allow (sdf) property names to start with $ % ~ or _ .
Ignore quotes in a property value used in --filter.
Update Windows installer and default_build.bat.
Remove MSVC90 from format CMakeLists.txt (now using MSVC100)
In the GUI, add a reference to the OpenBabel paper to the About screen and to a new splash screen.
* src/descriptor.cpp: std::string::back() is not a standard STL method.
  This failed to compile on linux with g++ 4.6.3.
* src/isomorphism.cpp: Fix mistak in implementation to make it go
  faster.
Remove double sized + in depiction to fix #3513745
Add note on dative bond forms to documentation of FastSearch format.
Add an external reference to the description of FP2.
Fix #3544142 crash when reading datafiles for FP3 and FP4 fingerprints.
There was a bug - accessing after the end of a std::string. This was tolerated in VC9 but not VC10. Since the bug has been there for 5 years I guess other compilers have become stricter too.
Put doxygen-generated "tag" file in doc for tools like Avogadro.
Don't add pH-dependent hydrogens.
Add distance geometry generation (still experimental).
scripts/openbabel-perl.i: Fix PR#3545604 as suggested and reported by David Koes.
Change comment on FPT_UNIQUEBITS and do not let it prevent a full isomorphism test in fastsearch. Pointed out by Tim.
Don't build obdistgen tool when Eigen is not found.
Fix from Björn Grüning.
Add test Python script from Andrew Dalke.
