- rename `screw_ie8` to `ie8`
- rename `mangle.except` to `mangle.reserved`
- rename `mangle.properties.ignore_quoted` to `mangle.properties.keep_quoted` 
- compact `sourceMap` options
- more stringent verification on input `options`
- toplevel shorthands

  - `minify()` used to `mangle_properties()` after `Compressor` but before `mangle_names()`
  - both will now do `Compressor`, `mangle_names()` then `mangle_properties()`
- `options.parse` / `--parse` for parser options beyond `bare_returns`
- add `mangle.properties.builtins` to disable built-in reserved list
  - disable with `--mangle-props builtins` on CLI
- `warnings` now off by default
- add `--warn` and `--verbose` on CLI
- drop `--enclose`
- drop `--export-all`
- drop `--reserved-file`
