python declarative UI
- remove XML testing feature
- add 2 modules: bpyml - generic, bpyml_ui - blender spesific. nothing uses these now.

==bpyml_ui module==
defines BPyML_BaseUI and its draw() function which uses the bpyml member of the class instance self.draw_data & self.draw_header_data.

This way declarative ui is opt-in and easy to use by using BPyML_BaseUI as a mix-in class.

==bpyml module==

This module translates a python like XML representation into XML
or simple python blender/ui function calls.
