Show sum of selected units in selection panel (as observer or also as player)

[fpre_O_O_O_O_O_O]

hi,

showing the sum of all selected units (maybe only military units count) per player in selection panel, when different units are selected, its helpful when viewing as a observer or also as player when wanting to know how many units in sum are involved in a fight.

It could be nice to have a math sum up sign (Sigma) as icon.
Maybe also in a tooltip some numbers to the classes hitted or f.e. how many champions, soldiers (normal), cavaleries (normal), workers, sieges, elephants, so the most important classes.

Or in general all classes in the selection as a massive tooltip showing the classes hitted in the selection as sum numbers (if the performance is not hurt to much).

Move tickets to In-game UI as UI & Simulation got some sub components.

(Sum as a player is already shown (​https://code.wildfiregames.com/source/0ad/browse/ps/trunk/binaries/data/mods/public/gui/session/selection_panels_middle/multiple_details_area.xml$23).)

A piece of information that the observer wants to learn quickly is the number of units per team that take a fight. For example 100 units (owned by players in team 1) vs 200 units (owned by players in team 2). This way one can estimate (and estimate more quickly) how good or bad the fight is for the participating players.

Currently the selected units are split by class, which means that the observer has to compute the sum of units per team, making it hard if not impossible to follow (10 sword infantry, 20 spear infantry and 30 skirmisher cavalry vs 20 spear cavalry, 2 healers, 3 women, 10 sword infantry and 8 skirmisher infantry).

So I guess the ticket is about grouping the units per team, or other easy means of obtaining the mentioned information.
