Convert acronyms correctly.

[saquibmian]

Currently acronyms are treated as a set of single-character parts. So URLOptions will be converted to [u, r, l, options]. This is basically never desirable.

Names should be split like so:

URLOptions → [url, options]
URL → [url]

Names should be formatted as such:

Style	Output
camelCase	urlOptions
PascalCase	UrlOptions
snake_case	url_options
kebab-case	url-options
Train-Case	Url-Options

Note that we should not entertain retaining whether something is an acronym (i.e., doing URLOptions → URL-Options) -- it becomes messy very fast, and a naming convention should be consistent. See this StackOverflow question for an example argument.
