2) fixes for issues with keys representing dynamic properties
i) all properties are converted to strings, in an approximation of JS
semantics
3) fix to handling of instance keys representing numbers in binary +;
now it understands that adding constant keys of type Number requires
adding a non-constant Number key to the lval
Note that this change actually breaks a couple of our unit tests. But,
it seems they were only passing by accident before anyway, and this change
at least leads to a more consistent handling of dynamic property accesses
with String vs. Number property names.
1) adopted the code from Rational for HTML handling
i) extended it to integrate better source mapping into IR
ii) integrated fixes from the old html processing to collect more info on forms
iii) added some copyright comments
2) updated version of jericho
3) added support for nu.validator for html5
4) added script to fetch html parser jars, and removed binary jar
