CCIMEDispatcher has fixed prompt on devices

[freezeepopprice]

Currently the prompt used by the CCIMEDispatcher is fixed as:

"please enter your word:"

It would be better if this could be set from the outside as it does with the current input string value. My suggestion would be to change the _focusDomInput method to the following (which allows the delegate to suggest the string:

    _focusDomInput:function (delegate) {
        if(cc.Browser.isMobile){
            this.impl._delegateWithIme = delegate;
            delegate.didAttachWithIME();
            //prompt
            this._currentInputString = delegate.getString ? delegate.getString() : "";
            var promptString = delegate.getPrompt ? delegate.getPrompt() : "please enter your word:";
            var userInput = prompt(promptString, this._currentInputString);
            if(userInput != null)
                this._processDomInputString(userInput);
            this.dispatchInsertText("\n", 1);
        }else{
            this.impl._delegateWithIme = delegate;
            this._currentInputString = delegate.getString ? delegate.getString() : "";
            delegate.didAttachWithIME();
            this._domInputControl.focus();
            this._domInputControl.value = this._currentInputString;
            this._domInputControlTranslate();
        }
    },

Then as a default the delegate in the textfield can provide a prompt (and can return the placeholder text). I do not know if this is considered a strong interface that needs to stay compatible with cocos2d-x though. The method added to the textfield would be.

    getPrompt:function () {
        return this._placeHolder;
    },

This is a good idea.
