Offer the option to generate fzpz/fzbz

Currently both tools only generate fzp/fzb and associated svgs that need to be copied into the program file structure (or the user's data folder). This is because the tool is optimized for large batch operations.

For individual use, it would be desired to generate "shareable" files (fzpz/fzbz) that can be imported into Fritzing via the GUI.
