This commit improves the CRM reporting by:
- adding new field on the report model
- providing new predefined filters for users
- renaming labels to be more precise
- reorganizing filter and group by
- remove wrong measure in report (probability and days
to close), as they were not correct when multiple
activity on a lead.
Main purpose is to ease finding usefull KPI for the
user, and make the activity reporting a bit less
confusing and limited.
It also now include all user messages (discussion
subtype) and note from activity (when marking activity
as done) in the reporting, so we can have a complete
analysis of action taken on the leads.
