Add-ons password storage
When uploading an add-on, there is now an option to store the password so that it doesn't need to be re-entered each time.
Fixes
Using arrow keys in small screen mode
Using the arrow keys to try and scroll on the add-ons manager while in small screen mode no longer closes the add-ons manager with an error message.
Updating add-ons from the multiplayer lobby
When someone is hosting a game which required some add-on and you have an outdated version of this add-on, the game proposes to update the add-on. This will now actually update the add-on when the player tells Wesnoth to update the outdated add-ons.
