Engine sets working directory based on exe

[stevewgr]

Description

Engine sets working directory based on exe. This behavior should be changed in order to make the working directory more flexible. One may run the game from a different directory, as in the case of debugging in Visual Studio. This messes up with stuff, like loading files correctly and such.

To Reproduce

Run SkyViewer editor in debug mode for example. Or put the SkyViewer.exe in game directory and run from there.

Tasks

Don't set the working directory based on the exe.
