Fix script execution issues and improve container creation

- Fixed syntax errors in build.func (duplicate export, unmatched quotes)
- Fixed color variable initialization by calling load_functions in core.func
- Replaced undefined function calls (post_to_api, post_update_to_api) with echo statements
- Fixed install script execution by copying scripts into container first
- Made create_lxc.sh executable
- Improved error handling and script sourcing
- Added missing core functions and tools
- Enhanced script downloader and local script management
