--User changes

-Add animation sequence creation to Fractorium.
 -Add two new options to EmberGenome which are used when generating an animation sequence.:
  --startcount: Add this number to the filename of each flame.
  --padding: Override the automatically calculated amount of padding zeroes added to each filename.

--Bug fixes
 -Prevent filenames in command line programs from using scientific notation when rendering a large number of frames.
 -Fix tab orders to match newer GUI items which were overlooked in previous releases.
 -Re-render previews if transparency value in the options dialog was changed. Re-rendering was previously only done if early clip or y axis up was changed.
 -Use transparency when rendering thumbnail previews.

--Code changes
 -Wrap EmberCommon.h in a namespace called EmberCommon.
 -Move FormatName() from EmberGenome to EmberCommon.h/cpp
 -Add a prefix parameter to EmberFile::DefaultFilename() to allow for creating a default filename for sequences.
 -When showing the final render dialog, allow specifying where it came from: the toolbar or the render sequence button.
 -Refactor all preview rendering code out into its own class hierarchy with overrides for the main window and the final render dialog.
 -Remove all preview render cancelling functions, they are now built into the new class hierarchy and a new render will not start until the previous one is stopped.
 -Add two new function ConstrainLow() and ConstrainHigh() which wrap constraining two min/max spinboxes to each others' values.
 -Add a bool to FractoriumEmberControllerBase::CopyEmberFile() to specify whether to copy the main file or the sequence file. This is somewhat of a hack and was done in a rush.
 -Add a bool to FractoriumEmberControllerBase::SetEmberFile() to specify whether to move the file rather than copy. This is used in FinalRenderEmberController and improves efficiency.
 -Add wrapper functions for variations filter dialog settings.
