Areloch 5525f8ecdd Converts all game, gui editor, and system classes to utilize assets 
Processed core, tools and default modules to utilize assets
Converted all console types that were string based, such as TypeImageFilename to utilize const char*/the string table, which avoids a lot of type swapping shenanigans and avoids string corruption
Removed unneeded MainEditor mockup module
Removed some unused/duplicate image assets from the tools

"%WaterObject surface rendering has the following general features:\n"
"\t- Waves represented by vertex undulation and user paramaters.\n"
"\t- Ripples represented by a normal map and user parameters.\n"
"\t- Refraction of underwater objects.\n"
"\t- Dynamic planar reflection or static cubemap reflection.\n"
"\t- Paramable water fog and color shift.\n\n"
