0b7c70f726 Update README.md to clarify --source-map filename option (#3137) 
Clarify that the --source-map filename option does NOT change the source map output filename but does set the 'file' attribute within the output source map. This was already documented in the API section of the README so I just copied that to the CLI options section, and a fragment to the CLI summary.

- 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
  - `ie8`
  - `keep_fnames`
  - `toplevel`
  - `warnings`
- support arrays and unquoted string values on CLI
- drop `fromString` from `minify()`
  - `minify()` no longer handles any `fs` operations
- unify order of operations for `mangle_properties()` on CLI & API
  - `bin/uglifyjs` used to `mangle_properties()` before even `Compressor`
  - `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`
  - use `--mangle reserved` instead
- drop `--reserve-domprops`
  - enabled by default, disable with `--mangle-props domprops`
- drop `--prefix`
  - use `--source-map base` instead
- drop `--lint`
- remove `bin/extract-props.js`
- limit exposure of internal APIs
- update documentations
