* add new dependency of p5-Test-Simple
* create the output dir if it does not exist (Thanx Paul Wolters!)
* added BUGS section to doc
* converted makegraph.t to Test::More and added some tests
* output dir no longer gets a trailing slash (good for OS/2?) and we use
File::Spec to construct output file names
* better reasons for skipping mails (string vs. some number)
