UI improvement : Add statistics in the bases list

[windware-ono]

I have about 8 groups each of them having a single base and it would feel very convenient if that screen can show the statistics values, so for example, I can see how many "Priority" columns are set as "High" in each base without going through each of them.

I see it doesn't have too much space to put complicated statistics, but a small horizontal table statistics for a count of a column should still fit and it might help people see the state of each bases at once.
