Condense script to single file, or a single file with optional supplements

[osanstrong]

Currently, the script uses some external files for data on elements or passive verbs. This allowed for quicker configuration when initially writing the script, however, may make the script marginally less intuitive to use.

It may be desirable to consolidate these datapoints into the preamble of the script, and give the user the option of providing custom data files themselves.

This issue can be closed either with a PR which either makes the bash script independent of these external data files, or if this feature is decided no longer desirable for those who would use it.
