Having a single GCF prevented GCC calling, but also exited the rest of
the function that writes the clustering and visualization results. Now
results are properly written in that specific case.

- Fixes #1 (thanks @suare012!)
- Updates dockerfiles
- Adds environment.yml for easier conda installation

- Added transAT-PKS-like to the set of rules (PKSother)

- '--mibig', '--mibig13'  and '--query_bgc' options are working again

- Added compatibility with antiSMASH 5 annotations
- Added a filter to select only individual cluster (antiSMASH 4) or
region (antiSMASH 5) files ('--include_gbk_str'). Previously, we had
been using 'final' as a string to filter out complete genome files, but
this string no longer appears in antiSMASH 5 files.
- domain_whitelist.txt: commented example domain
- domains_color_file.tsv: added random colors for more domains
