ea3430102c Add property name mangler 
We only touch properties that are present in an object literal, or which are
assigned to.  Example:

    x = { foo: 1 };
    x.bar = 2;
    x["baz"] = 3;
    x[cond ? "qwe" : "asd"] = 4;
    console.log(x.stuff);

The names "foo", "bar", "baz", "qwe" and "asd" will be mangled, and the
resulting mangled names will be used for the same properties throughout the
code.  The "stuff" will not be, since it's just referenced but never
assigned to.

This *will* break most of the code out there, but could work on carefully
written code: do not use eval, do not define methods or properties by
walking an array of names, etc.  Also, a comprehensive list of exclusions
needs to be passed, to avoid mangling properties that are standard in
JavaScript, DOM, used in external libraries etc.

d78ae20e64 Make empty source map values more reasonable in .minify() 
`"null"` isn't a very usable value. `JSON.parse(null)` also gives `null`, which makes this fully backwards compatible.

Closes #616

7f9bc9e863 Pass mangle options to figure_out_scope and compute_char_frequence 
Fix #219. Because the options were not set and `toplevel` is `false` by default, some toplevel names would sometimes not be mangled correctly.

0f80b1058d Resolve the relative path to lib files last 
This allows usage of UglifyJS on build systems which have a flat (or non-matching relative) directory structure for source files.

2bd8a118c2 define AST_Node.from_mozilla_ast(ast) 
returns an UglifyJS2 AST given a Mozilla AST.  Still needs some work to do
(need to create specific nodes like AST_SymbolRef, AST_SymbolLambda
etc. instead of base AST_Symbol, in order for the mangler/compressor to work
properly)
