Page up/down with side-buttons about mac-mouse-fix

[r3a1d3a1]

What works even better than Page Up/Down is sending multiple scroll events!
They get ignored if sent all at once, but with 20ms delay between them, they do the job of Page Up/Down, but more smoothly!
Furthermore, while Paging keys always get delivered to the window in focus, the scroll event simulation gets delivered to the window under the cursor, which IMO is far more desirable.

CGEventRef scroll = CGEventCreateScrollWheelEvent(NULL, kCGScrollEventUnitLine, 1, upwards ? -10 : 10);
CGEventPost(kCGHIDEventTap, scroll);
CFRelease(scroll);

I've used an NSTimer in a for-loop to send 7 of these 20ms apart.

My quick hack to do this is to change behavior of "Move between spaces" in InputParser.m as follows:
(Since I personally don't use multiple spaces that often)

added #include <Carbon/Carbon.h> on top as well (not shown above).

I'm not too familiar with XIBs and Objective-C, otherwise I'd have created a PR with this feature baked in as a 3rd option for side-buttons :)

I have a trackball with side buttons and no scroll wheel buttons, so having a "Scroll up/down" option for the Side Buttons would also be valuable for me.

Can you post a PR? I'm not sure where to add that but I'd love to try it out. A +1 for treating them as swipe up/swipe down instead of page up/page down.

Ah, nevermind, I see where you mention that you're not super familiar with ObjC/XIBs.. me either :(

Hey guys sorry for chiming in so late. You can now assign Page Up and Page Down to a mouse button in the new 2.0.0 Beta 2. Let me know what you think!
