cream port doesn't install all needed files

[Andriy Gapon]

After upgrade to vim7 and cream 0.36 I get complaints about at least the
following two missing functions on cream startup:
Cream_path_fullsystem
Cream_buffer_isspecial

These two functions are defined in the following files:
cream-lib-os.vim
cream-lib-win-tab-buf.vim

Both seems to be missing from CREAM_FILES variable in cream port Makefile.
I am not sure if these are the only files not being installed.
