Due to a countless number of changes made to the core that were not
fully understood, tested, or documented, it was decided to roll
everything back to the last known stable version (2.6.2).

Changes dropped include:
 - Witness needed
 - Shake
 - Frame SFX
 - Multiple custom objections
 - Multithreaded thumbnail generation
 - Looping
 - Various translation additions
 - "Mirror IC"
 - Color in IC log
 - An invocation of clang-format

Next time, work together and split your big fork into independently
testable feature branches.

This reverts commit bf8aad33de3b326f3a36cad33ced5d3acd7f2c24.
