commit bc45fe3263d34ef5f746f524687999c19bf7b779

    wave scale -> wave speed

commit ff96388b128c724c1198757bfa52f1935a263356
Author: Randy Heit <rheit@users.noreply.github.com>
Date:   Sun Mar 1 18:45:32 2015 -0600

    More sine quake fixes

commit 2a89749a6fe6d271b9fbdc218779f680afcf4cb6
Merge: 719dfbe 5456074
Author: MajorCooke <paul.growney22@gmail.com>
Date:   Sat Feb 28 20:37:22 2015 -0600

    Added QF_WAVE to A_QuakeEx.
    - Changes the random quakes into a sine wave (see Shadow Warrior/Rise of the Triad reboots, Hard Reset, etc.)
    - Added 3 properties to control waves per second along each individual axis. Only works with QF_WAVE.
    - Intensity X/Y/Z property becomes the amplitude of the wave.
    - Stacks with regular quakes, allowing shaking along the camera which must be called using A_QuakeEx WITHOUT the flag, or the other quaking functions.
    - Uses the youngest quake's time for positioning.

commit 54560741581e8d15cc7060e8e068cf85e9a4b432
Author: MajorCooke <paul.growney22@gmail.com>
Date:   Sat Feb 28 20:21:19 2015 -0600

    Recommitted recommended changes by Randi, with some modifications. Now, we should be finished!

commit 6f4473013411686d88fc185bdc1cc58b1035b0f1
Author: MajorCooke <paul.growney22@gmail.com>
Date:   Sat Feb 28 12:52:57 2015 -0600

    Finish this revert.

commit 467e53f9400f588a2ada9b32e7634cb1f4ad5066
Author: MajorCooke <paul.growney22@gmail.com>
Date:   Sat Feb 28 12:46:02 2015 -0600

    Reverted back to what was working.

commit da9de56a67efda08036e481fd5fccd5392ce6810
Author: MajorCooke <paul.growney22@gmail.com>
Date:   Thu Feb 26 18:53:20 2015 -0600

    Forgot this bit, for testing.

commit c5093d9bb97caf8478cefc32abc56a036feeea58
Author: MajorCooke <paul.growney22@gmail.com>
Date:   Thu Feb 26 18:52:46 2015 -0600

    Some more progress, but...
    - This did not solve anything. In fact, it did the opposite -- completely broke wave quakes. Now they only happen whenever a random quake is in progress.
    - Left in the commented code on purpose so Randi can test it.

commit 7e526405d2127cbb279f66008c8f8e55a5d497f3
Author: MajorCooke <paul.growney22@gmail.com>
Date:   Wed Feb 25 17:50:42 2015 -0600

    - Use newest waveform timer, not oldest.

commit 1356443609dbc6c7f46e081d0846816dc0836124
Author: MajorCooke <paul.growney22@gmail.com>
Date:   Wed Feb 25 17:32:09 2015 -0600

    - Got regular quakes to multiply onto sine quakes, but the vice versa needs fixing too.

commit d95796c94c70cd0229d4a6d30f69e3a7568b9588
Author: MajorCooke <paul.growney22@gmail.com>
Date:   Wed Feb 25 16:46:21 2015 -0600

    - Last hurdle. Now just need to figure out how to properly scale up and down.

commit 4bc3458e689155ce72c09776604d9eb4fa73d8be
Author: MajorCooke <paul.growney22@gmail.com>
Date:   Tue Feb 24 23:18:03 2015 -0600

    - Fixed the quakes being unstackable.

commit b51012d6d4ea065bf7f6fc9c1a0472966491f7af
Author: MajorCooke <paul.growney22@gmail.com>
Date:   Mon Feb 23 23:48:34 2015 -0600

    QF_WAVE renamed from SINE.
    - Lots of ground covered, but still more to go.
    - Still need to figure out how to make the camera properly shudder.

commit 427e4893193470bbf45415ffec70a0b69b8cccfd
Author: MajorCooke <paul.growney22@gmail.com>
Date:   Sun Feb 22 16:52:30 2015 -0600

    - Begin the groundworks for QF_SINE.
    - Need to figure out how to rework and manipulate the sine wave to move faster, and to allow going below 0 without breaking it too much.
