1. Cmakelists - move copy xml folder command to root file
2. - Move set python paths code to python module init funtction
- pci.c move python module init block code after checking model
to get paths before it runs.
- Fix set python path code to work with PYTHONPATH
- Update pci run script to work with PYTHONPATH
- Fix python finalize code
3. Change pcilib_script_s interacting method. Now it stores in hash.
4. Change names of some fucntions to more unified ones
5. Remove old unused function pcilib_xml_create_script_or_transform_view
6. cli - disable reading register after set if write_verification flag is off
7. Remove uninformative error messages fro Python wrap.
8. - Server.py - add read/write property/register command handling
- Add help message
- Correcting paths
