PATCH: Handle JavaScript attachment as a text so that it can be previewed.

Added by Wataru Hirayama about 4 years ago

Currently JavaScript attachment file can not be previewed because it's mime type is not 'text/*.'
In my environment JS attachment is found often, so it is inconvenient.

I here propose a patch that add an extention list in "is_text?" to define which file is explicitly handled as text.
Currently ".js" only, may be postscript or something like that.
