Summary:                    SWIG C# generates a DllImport line that doesn't
match the library name
Description: 
When creating C# bindings with UseSWIG like:

  swig_add_module(MyModuleCSharp csharp MyModule.i)

then SWIG will generate code containing

  [DllImport("MyModule", EntryPoint="...")]

but the library name generated by CMake will be something like
libMyModuleCSharp.so (note the 'CSharp' suffix). This causes the generated
bindings to crash unless the library and module names just happen to match.

SWIG provides an argument to set the DllImport name to something else. By
passing "-dllimport MyModuleCSharp" the DllImport line will contain the correct
library name.

  [DllImport("MyModuleCSharp", EntryPoint="...")]

Attached is a patch which implements this inside SWIG_MODULE_INITIALIZE.
