Mantaflow [Part 1]: Added preprocessed Mantaflow source files

Includes preprocessed Mantaflow source files for both OpenMP and TBB (if OpenMP is not present, TBB files will be used instead).

These files come directly from the Mantaflow repository. Future updates to the core fluid solver will take place by updating the files.

+ *  Here you can find the auto-generated documentation of the mantaflow framework.

+ *  One of the most useful parts is probably the list of python functions, classes and the C++
+ * kernels. Those can be found found in the ''Modules'' section. For python functions the
+ * parameters (e.g. Grids, Real or int values) are automatically transferred to and from python.
+ * Thus, this list is a good reference how to call the functions used in the example scenes.
