add reloading state to asset tracking,
convert most asset.isnull() checks on over to skipping out unless the errcode is ::Ok, or ::UsingFallback
add more errstriongcodes to hook up
skip load<type> execution if the asset loaded state is ::Ok
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
