Offer configuration of "lowercase words"

Currently conjunctions, pronouns, and prepositions are hard-coded into the module. (Words like 'and', 'the', 'it', 'they', etc.).

These should be configuration options available in an administration setting, that way you can easily adjust which words are always lower-case (except when the first word in the string.. perhaps that can also be configurable) when parsing the acronyms from the input string.
