[Seaside] no HTML entities for 8bit characters in UTF-8 encoding

[Kamil Kukura]

In order to have UTF-8 encoding working, there must be no expansion to 
html entities for characters over 128. I mean HtmlCharacters collection 
in WAAbstractHtmlBuilder. In fact, it is only okay for HTML's default 
ISO-8859-1 (western europe) enconding.

Here is what I have for international texts. I have derived 
WALocaleComponent from WAComponent which has only #renderClass modified 
so it uses WALocaleHtmlRenderer. Such renderer has method #textOf: which 
looks to class' internal dictionary of texts according to given symbol.
This dictionary is fed from XML file like:

<text id="buttonSend">An Unicode text encoded in UTF-8</text>

However, I need one more method because I need handle cases such as:
html submitButtonWithText: (html getTextOf: #buttonSend)


.. just my contribution to i18n
