HtmlBuilder: change all return error to Throw, update Element/StrinReplace

We do not return old style bool on error, we throw Exceptions: HtmlBuilderExcpetion

Element has more classes to set tag, id, etc with basic checks for valid data

String Replace to set strings is one array with key -> value entries

Errors thrown on index for element/replace blocks
