a4f6d46118 add option to mangle names even if eval/with is in use 
(for more fair comparison to Closure compiler)

a21f3c6cdd employ a better parser for command-line arguments 
to support passing commas in strings in for example:

    uglifyjs2 -cd TEST="'a,b'" <<EOF
    console.log(TEST);
    EOF

    → console.log("a,b")

42038fd67f Support input source map 
This is useful while compressing generated code; for example compressing JS
compiled by CoffeeScript (assuming you got a source map):

    uglifyjs2 --in-source-map generated.js.map \
              --source-map uglified.js.map \
              -o uglified.js

The above assumes you have a "generated.js.map" file which is the source
mapping between your CoffeeScript and the generated.js (compiled output from
CoffeeScript).  The name of the input file is not present in this example;
it will be fetched from the source map (but it can be passed manually too).

The output will be in "uglified.js" and the output map "uglified.js.map"
will actually map to the original CoffeeScript code, rather than to
generated.js.

5491e1d7b1 better support for multiple input files: 
- use a single AST_Toplevel node for all files
- keep original source filename in the tokens

924aa58060 more optimizations that v1 does and some cleanups 
- a = a + x ==> a+=x
- joining consecutive var statements (hoisting is not always desirable)
- x == false ==> x == 0, x != true ==> x != 1
- x, x ==> x; x = exp(), x ==> x = exp()
- discarding useless break-s

8e82d8d94c fixed some mess with symbols/scope 
- all symbols now have a `thedef` property which is a SymbolDef object,
  instead of the `uniq` that we had before (pointing to the first occurrence
  of the name as declaration).

- for undeclared symbols we still create a SymbolDef object in the toplevel
  scope but mark it "undeclared"

- we can now call figure_out_scope after squeezing, which is useful in order
  not to mangle names that were dropped by the squeezer

da407d46c6 checkpoint 
- discard statements with no side effects (unsafe? could be)
- safer hoist_vars (needs some revamping of scope/mangling)
