TankType filtering and 

Hello !

When using the "TankType" entity (which is project-specific), the loader displays all the types from any project, causing an extra long and confusing list of possible filters. So this adds filtering on the context's project.

Also, we want to be able to display publishes grouped by a custom field on the publish entity, but the filtering is hard-coded to filter on the "entity" or "task" field. This adds the flexibility to filter/group publishes by any field, through an additional "publish_field" setting (default still is "entity"). As an example, a "By User" tab is declared in the "entities" default value.

Thanks !
