Redmine Checklist plugin

Extends issues to store checklist items

About

Checklist Plugin creates simple checklists for Redmine issues. It handles the wiki tags and could be saved to the issue history log.

Unzip it into ../plugins/. This would result in a directory-path like:
```
../plugins/redmine_issue_checklist/init.rb
```

Migrate database and copy assets by following command:

bundle exec rake redmine:plugins NAME=redmine_issue_checklist RAILS_ENV=production

You now need to restart Redmine so that it shows the newly installed plugin in the list of installed plugins ("Administration -> Plugins").
Go to "Administration -> Plugins -> Redmine Issues Checklist plugin" and setup plugin global settings.
