Fix Value Schema not working in @media query

Fixes andrew/node-sass#90
This function was defined in the Header file, but
had been moved from the .cpp file. I'm assuming it
was removed since there aren't any special memory
handling requirements associated with a folder_context.
I could have removed the def from the header file,
but I felt it better to keep an extremely consistent
interface. Today, we don't have any special needs
with the folder_context, but in the future we could
want to do some other cleanup/etc. So, to fix this
issue, I created a simple drop-in sass_free_folder_context
method.

This issue was blocking Ruby from building the library.
Holy moly. Apparently my merge didn't work...

Merge pull request #111 from Nabellaleen/FixMediaQueryValueSchema

Fix Value Schema not working in @media query
[sass_interface] Need to call register_c_functions() after adding them to the context.
[context.cpp] Calling register_c_functions() from the constructor is pointless (and confusing).

The c_function_list is guaranteed to be length zero making the call a nop.
Reduce complexity by using strdup().
[eval_apply.cpp] Fix c_val_to_node when type is a list.
Add an extra opaque parameter for the c_function to store some data.

This is useful if you have to funnel a bunch of c_functions through a common
callback function (when writing a language adapter, for instance).
[sass_values.cpp] Set the list length when making a new c_list.
[eval_apply.cpp] Set c_args.list.length when calling c_functions.
[eval_apply.cpp] Don't forget the separator when converting lists in c_val_to_node().
