[Improvement] Production Queue currently adds 1 click

[DodgemasterDLux]

Vanilla:
Click on single item chooses next build project in city and closes the production banner

HB UI mod:
The production queue adds a lot of possibilities to manage a queue but if a player wants to select only one item and move on with other actions he needs to spend one more click to actually close the production banner.

Improvement:

LEFT CLICK adds one item to PROD Queue and closes production banner.
SHIFT+LEFT CLICK adds one item to PROD Queue and does not close production banner

All other user actions need to be checked but shouldn't make major issues.

Needs testing of course to see if this resolves. But current solution is a UX issue at the moment.
