Merge branch 'dialog_hotkey_fixes' into 'master'

Dialog hotkey fixes

Fix hotkeys in Arcane Combat and Chronomancy dialogs

Previously, pressing hotkeys (a,b,c...) had no effect in these dialogs. Now, hotkeys can be used to select the associated list option.

Also, I included a fix to Warden's Call short_name. This is not related to the other changes, but I think it's too small to make a separate branch. Previously, Warden's Call short_name did not have quotes around the value, so it was effectively nil. Now, the short_name is correctly assigned.
