Slightly improved Smari's strange error reporting habits.
.gitignore: Added more swap files (*.swo)
Translation: 3 more strings to Icelandic
Issue.deadline_discussions setting implemented and displayed (no functionality yet, since it's unclear how it's supposed to work)
Error reporting improved when IcePirate is malconfigured or not running
Improved HTML stripping from displayed Markdown content (should eventually be removed from content in database)
Fixed earlier commit (wrong import)
Fixed 500-error on JSON request when viewing issue but not logged in
Issue processing implemented, marking documents as adopted upon successful, finished vote
Fixed: Everyone should be part of the front polity if a front polity is configured at all
Bugfix: When a document is created but no content put in (no DocumentContent), view no longer crashes
