Implementing sass_free_folder_context() function.

Although sass_interface.h header contains the prototype of
void sass_free_folder_context(struct sass_folder_context *)
function, sass_interface.cpp hadn't implemented it.
This had caused link errors.
Merge branch 'master' of ../libsass into python
Don't free output_path

output_path field isn't made by libsass, so it should not be
free by sass_free_folder_context() function.
Merge branch 'master' of ../libsass into python
Removed types and leave only one function
Fixed broken tests
Include test data
Added CompileError type
Packaging
Include README.rst
