minor changes and added examples

[ricco386]

I have added examples dir with 2 new examples and moved existing zabbix_add_item into newly created examples directory I have also added ability to set logging level in zabbix_rcp_test when calling it from command line. Updated lincensing information from original project, and renamed readme file so it can have markup

I understand it is not a best idea to rename project on github, since it would break existing links. How ever I do think that scripts isnt the best name for the project and if possible it should be renamed.
