work on isf editor

added version to about window :: the source code editor now displays errors for malformed JSON blobs :: source code editor font size should respect the system zoom level for high-DPI displays on windows :: went through and removed last few remaining references to the 'Library' from the windows build (it referred to a path on macs for anyone who was curious) :: fixed a bug, converted shaders weren't being written correctly on windows :: fixed a bug, OpenSSL libraries werent being packaged up with the windows build, which resulted in an inability to contact shadertoy on many systems :: bumped version number to 2.9.8- due to a Qt bug, version numbers have to be truncated to three groups of numbers :: work on installer project, source tree should no longer get polluted with build files during a release build :: updated nlohmann json
