oUF: MovableFrames 

Changes from 1.15
- Handle headers that have no width defined.

Changes from 1.14
- No longer attempts to clear un-used initial positions before the first initial position table has been created.

Changes from 1.13
- Now correctly handles hidden group frames.
- Improved the unit guesswork so partypets, partytarget, maintank and mainassist group should be detected more often.

Changes from 1.12
- Ability to set scale on the frames by dragging an anchor located in the bottom right of the overlay.
- X position, Y position and scale can now be hand-tuned by clicking on the numbers in the option UI.
- Some minor clean-up.

Changes from 1.11
- Group frames will now show the backdrop, even when no frames are displayed.
- Bumped TOC interface version to 40100 (4.1).
- Update the subtitle as it was horribly outdated.
- Several small changes to allow embedding.

Changes from 1.10
- Added support for oUF 1.5.x, and the new header group formats.

Changes from 1.9
- Minor fix to work around events firing even though it's unregistered.

Changes from 1.8
- Should no longer attempt to move party/raid frames several times.
- Updated to work with both oUF 1.3.x and 1.4.x.

Changes from 1.7
- Move the frames back to their initial position when their entry is removed from the UI.

Changes from 1.6
- Yet another round of improvements on the frame name guessing. This will hopefully be the last.

Changes from 1.5
- Largely improved how frame names are guessed and added validation of the guessed names.

Changes from 1.4
- Correctly handle several levels of scaling.
- Also some minor code preparations for saving of default position.

Changes from 1.3
- Properly set the initial height of header frames that don't have any units yet.
- Don't wrap the unit label if the frame is too small to display it.
- Largely improved frame name guessing.

Changes from 1.2
- Made /omf <anything that isn't space> open the frame list interface.
- Child frames (such as party target) are no longer detached from their parents initially. Moving them will however do this.
- Attempt to describe the frames with more sane names. A quick example would be "oUF_PartyUnitButton1Target" that becomes party1target. This is also done in the interface list.

Changes from 1.1
- The frame list will no longer error out on empty data sets.

Changes from 1.0
- Party/raid frames that show the player and player's pet or target no longer gets confused with the real pet/target frame.
- Frames that don't have a legal position on the UI are temporary ignored. The downside with this is that they cannot be positioned until they have one.
