set execute bit only on executables

[Reimar Bauer]

currently all files in the development repostiory seems to have execute bit

on a linux System we should may be remove first all ritghts and set them afterwards to

cd mss
chmod -R a-rwx
chmod -R a+rwX
chmod a+x mslib/msui/mss_pyui.py
chmod a+x mslib/mswms/mss_wms_cl.py
chmod a+x mslib/mswms/mss_wms_wsgi.standalone_paste.py

The last one will be replaced by e.g. mswms.py

only directories and a few files should have execute bit set, fixes #40
