feat #305 remobe useless code

Ages ago we removed .bindableProperties from widgets. Unfortunately we forgot to remove it from all classes.
This does some cleaning of dead code.

fix #304 expected JSON response in RequestMgr

All request handler wipe out the failure response from the server. This prevents REST applications.
Moreover, using JSON the expected response should contain JSON also in case of errors.

fix #322 invalid html test

Html test contains two errors

1. disabled is a boolean attribute, so it's value should be 'disabled'
2. using border as style make testing IE painful, the returned value is "border-top/bottom/left/right"
Using color reduces the problem but anyway the return value is 'COLOR: black' : mixed case and no semicolon
fix #309 vertical splitter bug in IE9

In IE9 a vertical scrollbar can appear even in 0px width container (likely
a browser bug), this fixes that issue.

Pull request #323.
fix #303 checkValue error when no bindings

the initial fix for #303 introduces a regression when the widget value is not bound to the datamodel.
If you go from an invalid text a valid value the latter is lost.
moreover if you go from a valid value to an invalid text the widget's style is that of the helptext.

feat #329 Remove unnecessary code during Grunt build: part1

This commits brings a general-usage function to do recursive replacements
in the AST given the replacements conditions, and adds two sample visitors
that remove [$]descriptions from the beans and event definitions.

The visitors are also capable to compute the number of bytes saved in the
process (the number is displayed at the end of the build by a newly
created Grunt task).
fix #315 improved test case

This improves the test case pushed in
5dc63fd637810862291ce5e31a6688dac4556487. Under some circumstances, the
old test may fail.
feat #327 improve error messages in assertEquals/NotEquals/JsonEquals

1. Allow usage of %1 %2 in assertEquals messages

%1 and %2 are shortcuts for value1 and value2 params passed to
%assertEquals and can be used as placeholders in the error message.

This commit implements the feature (Assert.js) and changes some of the
unit tests to use the new capability.

2. Fix the obvious issue with the error message of
'assertNotEquals'.

3. Write serialized versions of JSON entities in assertJsonEquals
in case there's no default error message passed.
