Protist getting a dangerous free ride on its version

[pcm32]

Currently the scala code resolves the type of the organism based on string matching 'ensembl', 'wbsp', or 'genomes' on the path of the config file feed for that organism. Because our only protists organism resides inside ensembl AND ensembl version == ensembl protist version, this works out nicely for that protists.

Potential solutions:
1.- Move protist species to a 'protists' containing path, and inject the version for protists as a separate argument.
2.- Make scala code rely on the type written inside the species config file (inside annsrc), in the field 'type', and inject the version of protist as a separate argument.

In the meantime, we are safe since the two versions match, but this shouldn't be left for long.
