Minifies the given
We then march through the token list and collapse certain tokens down to their smallest possible representation. If they're still included in the final results we only want to include them at their shortest.
Runs of multiple whitespace characters are reduced down to a single whitespace character. If the whitespace contains any "end of line" (EOL) characters, then the end result is the first EOL character encountered. Otherwise, the result is the first whitespace character in the run.
We then go back through the token list and prune and remove un-necessary tokens.
Wherever possible, whitespace is removed; before+after comment blocks, and before+after various symbols/sigils.
Comments that are either (a) IE conditional compilation comments, or that (b) contain the word "copyright" in them are preserved. All other comments (line and block) are removed.
We keep everything else; identifiers, quoted literal strings, symbols/sigils, etc.
