Clean up edit_* pages, some config changes, bug fixes

- Class Basic convert string to bytes fix
- admin edit_* pages do not need JS except pop call, moved that into the
template and do not load any other JS anymore
- changed the EDIT_STYLESHEET/JAVACSRIPT names to ADMIN_ to give them
the proper name that they are admin based functions
- paths are in an extra config file
- plan on moving edit_* css rules into a special CSS file just for this
