Update the title to 
Deploy StringBuilder::appendNumber() and StringBuilder::appendLiteral() in more place

typo: String::appned()

This whole function should use String Operators.

I doubt this compile, StringBuilder::appendLiteral() is resolved at compile time.
It should be:
    if (enableds[i])
        source.appendLiteral("true");
    else
        source.appendLiteral("false");

Ditto.

Gosh, that's sad.

Typo: place->places

Hum, this would actually be even better in one append():
    source.appendLiteral("</style></head><body>\n"
                         "<script>\n"
                         "window.addEventListener('load', function () {");

> Source/WebKit/blackberry/WebCoreSupport/DatePickerClient.cpp:98

ditto, one literal would be better.

Ditto.

Ditto.

> Source/WebKit/blackberry/WebCoreSupport/SelectPopupClient.cpp:132

Ditto.

It isn’t so great that this creates three String objects and then destroys two. We should figure out how to make uses like this efficient. It might even have been better to have this continue to use StringBuilder.

There is no StringBuilder::number() for floats. At the moment, this is the best solution.

We should have StringBuilder::number() for double and a StringOperator for numbers, but that is not there yet.

I'm working on, but I want to cleanup some parts first. Otherwise I have to duplicate too much code.
