GridField actions should take highest priority in order of screen layout

[robbieaverill]

Example:

The order of precedence should be:

• Any alerts for the user
• The actions toolbar (if one exists) (e.g. GridField actions in this case)
• Any content

In this case this means moving the report description to a position in between the GridField actions toolbar and the GridField itself.

@newleeland lets go over this tomorrow

From memory there is a Gridfield header which normally sits under the actions (above gridfield), if true then perhaps the Version details should become the header.

Thanks @clarkepaul, good to know and I'll add that to the issue for this report - this ticket was more of a core refactoring ticket for future so we can move the description into the right place in the report (ensuring actions are shown first)

For information, @ScopeyNZ added a GridFieldHtmlFragment class to allow HTML to be added into the GridField area in the silverstripe-maintenance module. This kind of thing would need to be ported into core to allow us to add report titles and descriptions between the report actions toolbar and the report itself (both GridField and/or components of) since the report title and description are currently FormFields in the FieldList alongside the report's GridField.
