v.3.4.0.13

A patch dealing with a number of less common issues.

Editor:

• Fixed #if(n)ver preprocessor directive failed to properly compare versions
  if the current and required versions have different number of digits.

Engine:

• Returned support for some older config options related to graphics mode,
  so that the engine would be able to use old config files.
• Fixed graphics mode initialization failure in certain less common setup
  cases, such as when requested window size was larger than current
  desktop resolution, or when the final mode appeared smaller than the
  precalculated one.
• Fixed couple of memory leaks occuring when saved game is restored.
• Fixed rare crash when restoring a game while having unreleased DrawingSurface
  pointers.
• Fixed compilation in C++11 mode.

WinSetup:

• Fixed "native game resolution" mode choice was not properly restored when
  loading config file.
