DESCRIPTION

This adds an “application” context for file MIME types, joining the likes of “audio”, “video”, etc--because I found it useful and hope that others might, too. Example MIME types this covers:

⋅ application/json
⋅ application/x-bytecode.python
⋅ application/x-object

This also changes MIME checks to be more watertight/pedantic, because “textiles” are not the same thing as “text”.

MOTIVATION AND CONTEXT

Differentiation of files based on type helps aid in navigation.
