Add project configuration and build tools

- Introduced new scripts for project generation and synthesis (dodo.py, generate_prj.py, generate_scr.py, run_xst.py).
- Implemented configuration parsing for VHDL sources and project settings (config.py).
- Added default configuration values (defaults.py).
- Updated .gitignore to include additional file types.
- Created test cases for project generation and configuration parsing (test_generate_prj.py, test_generate_scr.py, test_project_cfg.py).
