Statistics Improvements

[alfa1]

My member like to see the following statistics for their groups:
- New Members
- Group Forum Posts
- Group Forum Threads
- New Media
- New Events

My members don't understand this and don't need this:

- Events Public
- Events Member
- Events Admin
- Posts share via Members Only
- Posts share via Staffs Only
- Comments on post shared via Public
- Comments on post shared via Members Only
- Comments on post shared via Staffs Only

Right now the statistic page is too confusing for my members. They don't understand the page and because of this they cannot use it.

Please improve this.

There is no way to set which statistic is loaded as default content at page load. Currently this always loads:
- Posts share via Members Only
This scares members away.

My suggestion to improve this:
- set 'new members' and 'Group Forum Posts' default content at page load.
