Merge pull request #16 from orex/master

Some bug fixes and improvement: cif format, OBPairTemplate.
Moved the C99 support headers to windows-msvc

The C99 support headers do not need any library, and should work with
any version of MSVC, whereas the xdr and cairo headers are tied to a
particular version of some libraries that are paired with binary
prebuild libraries.

It should now be possible to build on any MSVC toolchain if all
dependencies are built correctly.
Merge remote-tracking branch 'upstream/master' into mdlextension
Made the CairoPainter object a private variable to the class again instead of a local var in WriteMolecule(). I got errors when trying to depict multiple molecules otherwise.
Made hash bonds draw with line width 1, required adding the function GetPenWidth to the different painters to be able to reset the pen width after drawing the bond.
Added the -b and -B options to pngformat to allow changes of colors when creating pngs.
Added -xm option for possibility to "crop" output image to a close bounding box of a single molecule.
Extend parsing of lattice vectors in pwscf.
Changed the metrics calculation in cairopainter to give nicer layout of text labels with sub and superscripts.

Extend parsing of lattice vectors in pwscf.
1. Use obsharedptr instead of shared_ptr. obsharedptr is #defined to the appropriate value
2. Add support for shared_ptrs to Python bindings. The following code now works:

r = OBReaction()
m = OBMol()
r.AddReactant(m)
