If welcome is enabled, use it to recover from a forgotten password (Closes hhucn/adhocracy.hhu_theme#243)
Improve password reset message when welcome_back is enabled
Remove useless files.

alternate login form (hhucn/adhocracy.hhu_theme#168)

pep8
Simplify registration support email
Secret voting (hhucn/adhocracy.hhu_theme#209)
Add a configuration option that should prevent users from seeing individual votes (Experimental)
Do not emit voting events when secret voting is active (hhucn/adhocracy.hhu_theme#209)
Remove unused import
Generate welcome link in user profile

Often, an administrator wants to assist a user who forgot their password, or has just been imported in. Add a simple button in the user details, where global administrators can (if welcome is enabled) generate a welcome link for users.
Extend instance import/export (hhucn/adhocracy.hhu_theme#224)

Add new properties and tests for import/export
Log errors in link creation
Pass on kwargs when generating comment URLs (hhucn/adhocracy.hhu_theme#65)
Always use absolute URLs for event links (Closes hhucn/adhocracy.hhu_theme#65)
