Add a wrapper script for building the environment

[darcyabjones]

What kind of feature are you proposing?

Currently, registering the proprietary source files involves running a few commands, and they're different for conda, docker, and singularity.
It would be good to make this process a single command that can take all source files and build it while you make a coffee.

Describe the solution you'd like
Probably the best solution would be to have something like the nextflow install method.

e.g.

curl -s "https://whereever.com/predector-env.sh" | sh - --signalp3 ./signalp3.tar.gz ...

I'm unsure if you can pipe the script to stdin of sh like that and still provide command line parameters, but it should be possible.

The reason that I like this idea, is that potentially it could make the build process look the same for each of the environments.

curl -s "https://whereever.com/predector-env-conda.sh" | sh - --signalp3 ./signalp3.tar.gz ...
curl -s "https://whereever.com/predector-env-docker.sh" | sh - --signalp3 ./signalp3.tar.gz ...
curl -s "https://whereever.com/predector-env-singularity.sh" | sh - --signalp3 ./signalp3.tar.gz ...

For docker the command is almost identical, but it would simplify things for conda and singularity.
I'm a bit unsure about this. I think the full version should be documented somewhere, but this might be a good "easy-install" method.
