Multiple `Click()` param issues

[ike709]

Code/Testing

Test code:

/client/New()
    ..()
    show_popup_menus = FALSE

/client/Click(object,location,control,params)
    src << "[params]"

I then proceeded to left, middle, and then right click once each.

BYOND:

icon-x=21;icon-y=17;left=1;button=left;screen-loc=6:21,7:17
icon-x=20;icon-y=17;middle=1;button=middle;screen-loc=6:20,7:17
icon-x=20;icon-y=17;right=1;button=right;screen-loc=6:20,7:17

OpenDream (can't highlight the text to directly copy it):

Issues summary:

• [x] left=1 is not set by OpenDream when left-clicking. Edit: Fixed by https://github.com/OpenDreamProject/OpenDream/pull/1929
• [x] button parameter is missing. Fixed by https://github.com/OpenDreamProject/OpenDream/pull/1929
• [x] Formatting issues with screen-loc (OD doesn't seem to be passing numerical values at all?).
• [x] Param order is different between BYOND and OD. This shouldn't matter but it's a trivial fix.

Middle mouse doing nothing is documented in https://github.com/OpenDreamProject/OpenDream/issues/1925
