Updated the server's PCRE components to 7.0

- dll, library, header
- cleaned the only existing example and moved it to /samples
- changed its interface a bit, now it uses $@ instead of $ to store the parsed result
- /!\ adjust your scripts if you are using npc regexp parsing /!\

+statments. The code in ./configure greps out the version numbers by using "cut"
