[Users] Keeping new filtering/processing headers in drop down lists

[Brian Morrison]

I've noticed that when using news accounts (and it might be the case
for email too) any new headers I enter such as NNTP-Posting-Host or
Injection-Info are not added to the drop down list and hence I have to
re-enter them every time I want to add a new filtering or processing
rule that uses them.

Is there a file somewhere that I should be adding these entries to
myself or could Claws be modified so that it saves unknown entries for
each drop down list?
