--User changes

-Add variations changes to the list of functionality that can be applied to all xforms using the Select tab.
 -Allow for graphical affine adjustments to apply to multiple selected xforms.
 -Slight optimization of the pie variation.
 -Undo state is only saved when the render completes and the mouse buttons are released. This helps avoid intermediate steps for quickly completing renders while dragging.
 -Add some keyboard shortcuts for toolbar and menu items.
 -Make info tab tree always expanded.

--Bug fixes
 -Make precalcs for all hypertile variations safer by using Zeps() for denominators.
 -Changing the current xform with more than one selected would set all xform's color index value that of the current one.
 -Use hard found palette path information for randoms as well.
 -OpenCL build and assignment errors for Z value in epispiral variation.
 -Unitialized local variables in hexaplay3D, crob, pRose3D.

--Code changes
 -Change static member variables from m_ to s_.
 -Get rid of excessive endl and replace with "\n".
 -Remove old IMAGEGL2D define from before Nvidia supported OpenCL 1.2.
 -Remove old CriticalSection code and use std::recursive_mutex.
 -Make Affine2D Rotate() and RotateTrans() take radians instead of angles.
 -More C++11 work.
 -General cleanup.
