CRM-15162 - crmCaseType - Update default activity-types (Open Case, Email, Follow up, Meeting, Phone Call)
CRM-15166 - crmCaseType/edit.html - Don't allow deletion of the standard timeline
CRM-15166 - crmCaseType/activitySetDetails.html - Lock the name by default
CRM-15166 - crmCaseType/timelineTable.html - Don't allow removal of the standard timeline's "Open Case".

Note: If (for some bizarre/erroneous reason) an admin added the "Open Case" activity to another
timeline, then it would be reasonable to delete it.
