#132 Add property "wrapper.user.home"

[Matthew T. Adams]

Add a configuration property that is a portable means of getting the equivalent of the Java system property "user.home".

Currently, you have to use a non-portable strategy like "#include %HOME%/.foo/bar.conf" (Unix flavor) and "%HOMEDRIVE%%HOMEPATH%/.foo/bar.conf" (Windows) and count on the fact that #include'd files that aren't found are ignored.
