- added gitattributes to ensure files always have the same format (UNIX LF) on any developer platform anywhere.

- whitespace police run: TABS=4 spaces, trim trailing - prevent later commit diffs due to WS cleanup by developer editors.
- added 'hot to build postal' description in the README, mentioning `anvil`

- added Makefile which can be used to run `anvil` by running `make`. It also implicitly documents the dependencies

- updated the `package.json` NPM INSTALL file to install anvil and anvil.uglify plugin for the developer build process.
- regenerated postal.js by `anvil` and `Makefile`

- added a `clean` target in the Makefile, which nukes generated (output) files. Run `make clean && make` to force rebuilding all postal targets.
