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
* Made use of dStrIsEmpty in more locations (and fixed it :P)
* Removed commented-out code
* Corrected default params
* Fixed some console warning formats
* Removed tabs
* Corrected setExtent API
