h4h5tools

Purpose:
    Organize h4h5tool project files.
Description:
1. All.dsw and all.dsp were located under h4h5tools/lib. Since they also described
h4toh5 and h5toh4 utilities, so the location causes confusions.
2. Add another project file called h4toh5utiltest to help use create their own
testing files.
Solution:
1. Create a new folder called proj that is parallel to lib and utils, put all.dsw
and all.dsp in that folder.
2. Add h4toh5util project.
