v6.15.1

Another small release, with a handful of fixes and minor improvements that make working in the platform a little smoother.

Improved user experience:

• In the web app we now validate the project name. Names longer than 255 characters are no longer accepted, so you no longer run into an error when saving.
• In the vote app we now show more clearly whether your vote has been saved, so you can be sure your input was recorded.

Bug fixes:

• In the web app you can create new registers based on a template or an existing register normally again. This was unintentionally restricted in the previous release.
• In the brainstorm app, opening a tab to a brainstorm that had already been closed left participants on a broken page. Participants are now neatly redirected to a session not found page.
