filters: export mime type and filename in env

Browse source 
Export AERC_MIME_TYPE and AERC_FILENAME in the filters command
environment. This allows dynamic coloring with tools that require
a filename and/or a mime type to determine the syntax.

Update docs and add example use in the default config file.
