Applied 2 more internal LoaderMgr interfaces for
gobally manage the font data resources.
The next function is introduced for lookup the existing loader
with the font name (key)
- static LoaderMgr::LoadModule* loader(const char* key);
The next function is introduced to free the existing loader
with the loader source(file path)
- static bool retrieve(const string& path);
Additionally implements the base loader to bind the ttf loader.
The loader cache is applied to conserve memory.
If the input data is already present in loaders,
the loader cache will promptly return the active loader.
This results in a lot of memory savings for the duplicated resources.
