Subject: Save user IMAP flags in separate array.
X-Git-Url: https://git.internetallee.de/?a=commitdiff_plain;h=57a595f9d9c400dd69e82c4d4c5e19fbd141cbc2;p=horde.git

Save user IMAP flags in separate array.

Allows for easier changing of system flags in the future, instead of
having to traverse through all user pref entries.
