Implement Phase 1: Auto-loading for ztools and Silo addons

- Add src/Mod/Create/ module to handle addon loading
- Init.py adds mods/ztools and mods/silo to sys.path at startup
- InitGui.py loads workbenches from addon InitGui.py files
- CMakeLists.txt installs Create module and mods/ directory
- Set ZToolsWorkbench as default startup workbench in preferences
