funannotate v1.5.2

• restructure augustus accessory scripts calls so that they don't have to be in same location as the exe, i.e. this used to be a bug if you used conda installed augustus as it puts the scripts in a different location than the default augustus release folder
• added a check to busco routine to default to a single thread if tblastn version is found that might have multithread issues
• allow a min number of gene models to use for Augustus training, --min_training_models in funannotate predict
• limit genemark to 64 cpus -- it will die if you try to give it more
• fix shortBAM declaration in funannotate update
• for genemark-ET set score of introns to 500, otherwise seems to be dying.
• updated weights for different gene models -- would be nice to have this be a customizable option....
