Removed tgi_load() and all corresponding infrastructure. The idea behind tgi_load() was to be able to describe a TGI mode in a target-neutral way by resolution and colordepth. However it turned out that there arn't any cc65 targets sharing any resolution. As a result the only working target-independent approach for a TGI program is to call tgi_loaddriver(tgi_stddrv); and then look up the resolution provided - and to adapt to that resolution.
