Keep references to textures and samplers in descriptors

Browse Source 
Previously, if the TextureManager was recreated, e.g. when changing the texture paths, all loaded textures were deleted, even if currently in use by a preset. Storing textures and samplers as shared pointers instead of weak pointers will make sure the objects are kept alive until the preset is unloaded.
