build CSharp bindings in SOURCE_DIR
Fix skipping molecules while using OBConversion::Read() method (mainly for bindings).
Fix compile problem due to use of FastRotorSearch without Eigen
Move OBForceField::FastRotorSearch from confsearch.cpp to forcefield.cpp as it does not depend on Eigen (unlike the other contents of confsearch.cpp). This should fix the compile problem (see the CDashboard).
Initial commit for EQeq crystal charge equilibration method

Run through python with

```
eqeq = pybel.ob.OBChargeModel_FindType("eqeq")
eqeq.ComputeCharges(mol.OBMol)
```

Patch from Roger to fix CONECT record output
Test case:
obabel -:CS(=O)(=O)C -opdb
Before:
CONECT    1    2
CONECT    2    1    3    4    5
CONECT    2 ****Bug or almost bug****
CONECT    3    2
CONECT    4    2
CONECT    5    2
After:
CONECT    1    2
CONECT    2    1    3    4    5
CONECT    3    2
CONECT    4    2
CONECT    5    2

Note to self: Where is that patch (from Astex) for multiple bonds in CONECT records that I applied years ago? Something's up.
Patch from Roger to enable Mol file support for atom classes
With this patch, MOL files now read in atom class information (3rd from final column in atom block) by default, and write it out if the "-xa" option is specified. This is the same as with the SMILES format.

Test case roundtripping SMI->MOL->SMI:
obabel -:[CH4:1] -omol -xa | obabel -imol -osmi -xa
[CH4:1]
