e130dc3fbb [loose parser] Use ✖ rather than question mark for placeholders 
This way, attempts to re-parse the pretty-printed code won't
be confused by the question marks.

038e438949 Add a loose parser 
For getting a halfway meaningful AST out of code that may contain
syntax errors.

Use case: analyzing code as the user is editing it.

cade51347a Remove trackComments, add onComment option 
trackComments was too obscure and complicated, and not all that useful.

f6e0182a3a Fixes sourceFile option. 
When setting the .prototype.source the sourceFile variable is undefined, and
setting the sourceFile option doesn't change the .source property on the
prototype anymore.

By setting the .source property inside the node_loc_t constructor, the correct
sourceFile is set in the loc object.

5b19196bac Give true/false/null literals a raw property 
In the generated ast, "null"/"true"/"false" are "Literal" nodes.
As every "Literal" node has a 'raw' property,
When i am doing something with the ast using python,
the 3 "Literal"s caused some problem.
make the 3 "Literal"s have 'raw' property.

905124c291 Assign parenthesized expressions a range that includes the parens 
This way, composite expressions that they are part of won't get bogus
unsyntactic substrings as their range (i.e. in '(1)+1', the binop expression
would span '1)+1').

Closes #14
