Make usage in README more readable.

This isn't perfect, but I think it is much more readable than it used to be.

files. Specify `--output` (`-o`) to declare the output file. Otherwise the
output goes to STDOUT.
The available options are:
--source-map Specify an output file where to generate source map.
[string]
--source-map-root The path to the original source to be included in the
source map. [string]
--source-map-url The path to the source map to be added in //#
sourceMappingURL. Defaults to the value passed with
--source-map. [string]
--in-source-map Input source map, useful if you're compressing JS that was
generated from some other original code.
--screw-ie8 Pass this flag if you don't care about full compliance
with Internet Explorer 6-8 quirks (by default UglifyJS
will try to be IE-proof). [boolean]
--expr Parse a single expression, rather than a program (for
parsing JSON) [boolean]
-p, --prefix Skip prefix for original filenames that appear in source
maps. For example -p 3 will drop 3 directories from file
names and ensure they are relative paths. You can also
specify -p relative, which will make UglifyJS figure out
itself the relative paths between original sources, the
source map and the output file. [string]
-o, --output Output file (default STDOUT).
-b, --beautify Beautify output/specify output options. [string]
-m, --mangle Mangle names/pass mangler options. [string]
-r, --reserved Reserved names to exclude from mangling.
-c, --compress Enable compressor/pass compressor options. Pass options
like -c hoist_vars=false,if_return=false. Use -c with no
argument to use the default compression options. [string]
-d, --define Global definitions [string]
-e, --enclose Embed everything in a big function, with a configurable
parameter/argument list. [string]
--comments Preserve copyright comments in the output. By default this
works like Google Closure, keeping JSDoc-style comments
that contain "@license" or "@preserve". You can optionally
pass one of the following arguments to this flag:
- "all" to keep all comments
- a valid JS regexp (needs to start with a slash) to keep
only comments that match.
Note that currently not *all* comments can be kept when
compression is on, because of dead code removal or
cascading statements into sequences. [string]
--stats Display operations run time on STDERR. [boolean]
--acorn Use Acorn for parsing. [boolean]
--spidermonkey Assume input files are SpiderMonkey AST format (as JSON).
[boolean]
--self Build itself (UglifyJS2) as a library (implies
--wrap=UglifyJS --export-all) [boolean]
--wrap Embed everything in a big function, making the “exports”
and “global” variables available. You need to pass an
argument to this option to specify the name that your
module will take when included in, say, a browser.
[string]
--export-all Only used when --wrap, this tells UglifyJS to add code to
automatically export all globals. [boolean]
--lint Display some scope warnings [boolean]
-v, --verbose Verbose [boolean]
-V, --version Print version number and exit. [boolean]
