One click queue system added, which affects gameplay completely.

Previously: After clicking on one thing, you could not click on another thing before 1 second had passed, and had to spam until 1 second had passed.
Now: After one click, if there's a second click right after, it will be queued and executed automatically after the 1 second has passed.

Tried to remove redundant DblClick() entries and changed them to QueueClick() where appropriate. Report for bugs.

Updated change log. :-)
