Add Work Time to unit middle-click menu

[jwrober]

Is your feature request related to a problem? Please describe. Unless you know the math and can do it in your head, it is hard for a player to know how long a Workers unit will take to alter a tile's terrain (e.g. irrigate, build road, forest->swamp, etc)

Describe the solution you'd like The general thinking is to add this to the middle-click popup menu like we do for all units. There is a view menu to show combat information as an example. Enable another view menu item to show worker tasks and then add some entries to the middle-click. For example, you have a vv Workers selected and you middle-click a tile. The pop-up would tell the player how many turns to do a collection of tasks to the tile based on the unit selected.

Describe alternatives you've considered Does not have to be in the middle-click pop-up as it could get kind of big. Could also be a pop up widget that is separate from the middle-click. The idea is the same, you have a Workers/Engineers type unit selected and you pick a tile and the game gives you some intel on how long it would take to do work on the tile.

Maybe this could be shown on top of the unit actions bar buttons.

I have a commit (415d813cf5f4406306064063c9dea9afc5071a1f) in my local, that displays the turn_founded for a city in the popup info. Testing shows, that you can rely on turn_founded only for your own cities.

For foreign cities, after reloading a saved game, turn_founded seems to contain the turn number when the game was reloaded. Even before reloading I had the impression, that turn_founded displayed the turn number when I discovered the city rather than when it was founded by the enemy, but I didn't check this any further.
