clean up suiteHistoryXML.vm
Add todo’s for suite xml formatter.
Make SuireExecutionReportFormatter.suiteExecutionReport private.

Move getRootPageName() and getFitNesseVersion() down to CachingSuiteXmlFormatter.
New Suite formatter: SuiteXmlReformatter.

It formats the XML based on the history formatter. This was partly the case for the (old) CachingSuiteXmlFormatter.
Remove CachingSuiteXmlFormatter.

We now have a more solid one that’s using this history formatter to the full.
Merge SuiteHistoryFormatter and SuiteExecutionReportFormatter.

One purpose, one class.
