Revert "fixed character encoding in lynx"

This was not a fix at all.

This reverts commit e96d31feca34a073f29e88b16571bdc9303986ce.
handle links with urlview
don't quote %s, mailcap will do this for you
fixed mailcap entries for lynx and w3m

lynx: -display_charset is the charset for the terminal output only and has
nothing to do with the character encoding of the html mail.
avoid unnecessary key press
sent, drafts and templates are no mailboxes
don't add address of the author to subject

1)
set forward_format="[%a: %s]" is the default, so this line is superfluous

2)
address of the author is redundant information an bloats the subject line
unnecessarily
fixed problem with character encoding of attachments
moved cache directory
added print command
fixed comments and clean-up
No reverse_name, please!
