ren_ext v1.26

(this is my first release on github.)
ren_ext is an regexp-based flexible file and dir renaming tool. just place the file where ever you want and add the directory to your PATH environment variable.
the perl script is a few years old and has been improved over the time. right before this release I changed the command line parsing and some cli params, but I hope, that it should work fine now.
If it does not, please send me an e-mail or use the github-bugtracker.
