When using periods in template filenames, these files would be suggested in the Add Template screen. However, when you would choose such a file, say “my.template.php”, the resulting template name would become “my-template”. You would then be notified that the template lacks a file, even though you created it from ProcessWire’s file suggestion.

This PR uses the same sanitizer method templateName() to filter suggested files which is also used to sanitize template names. Before, only name() was used, which allows periods. Thus, “my.template.php” is no longer suggested.

In my case, that’s what I want anyway, because I’m using the period to denote partials related to the template.

Thank you!
