[IMP] web, *: add kanban column progress bars

* crm, project

records whose value of a given field are the same in the column.

<progressbar field="<name of the field to use for subgroups>"

             sum="<name of the field to sum or nothing to use total number of records>"/>

Also:
- Properly update record model data's parentID when moving a record
- ...
