Release notes freestyler v6.2507.18

Release summary

Bugfix for xml sitemap:
The xml sitemap did not generate the last entry. This was fixed.

Bugfix for mailroom posts resulting in server issues:
When a form is being posted with an invalid extrasendto unid, the domino html server builds up unclosed tasks and cpu usage. Investigation showed that the native HCL call getDocumentByUNID() cause these issues when called with an improper unid format (and no errorhandler activated).
This was fixed by extending the following mailroom routines with error handlers:
- getFS3Formsettings()  
- getExtrasendtosettings()
This release was given extra priority (done inbetween) due to the fact that form spamming could lead to server issues.
