filtered/sorted statuses in the dashboard

[meinmicha]

Is your feature request related to a problem? Please describe.
At the moment all statuses of all tracker are shown in the dashboard.

• That handling is correct for showing all projects.
• By selecting a specific project still all in the system-wide config available statuses are visible.

Especially for larger Redmine
environments or more diverse projects with different trackers and workflows the current way of displaying the statuses as columns are not very good. In that way a very nice and easy to hand plugin is unfortunately not usable.

Describe the solution you'd like

• Only show the available statuses for issues that are currently (active) available in one project according to the used/configured tracker.

Describe alternatives you've considered

• Add a configuration on the plugin config page for number of columns and name of these columns and let the admin manually sort all status to these just add preset on columns.

Additional context
It is already a very easy and neat plugin, it's quite nice to work with it, thank you :)
