a LabeledStatement should be in fact a StatementWithBody
...
This fixes output for:
if (foo) {
moo: if (bar) {
break moo;
}
} else {
baz();
}
(the labeled statement must be outputted inside brackets)

replace nodes with a single statement.
looks stable for now, though mess begins to sink in. need to review the AST
hierarchy.

fix code generator for this case:
...
if (foo) {
with (bar)
if (baz)
x();
} else y();
(the compressor removes the brackets since the consequent consists of a
single statement, but the codegen must include the brackets because
otherwise the `else` would refer to the inner `if`)

fix output for certain edge cases
...
the statements if, for, do, while and with might have an AST_EmptyStatement
as body; if that's the case, we need to make sure that the semicolon gets in
the output.

some reorganization

(moved pretty much everything that relates to scope in scope.js, added a
module for NodeJS that can be used with require() and exports everything.)

more fixes:
...
- added walker for AST_ObjectProperty
- handle redefinitions properly (only mangle one symbol, make them all point
to a single definition)
DynarchLIB seems to run fine after mangling + compressed output.

big speed improvement (observable when beautify = false)
...
who would have thought that str.charAt(str.length - 1) is not a constant,
instant operation? seems to get slower and slower as the string grows.
0.6s vs. 3s
