Completely overhaul after/ftplugin files

Should have done some of this in separate commits; oh well.

* Rewrite headers for each ftplugin
* Require Vim version >= 7.0, and thereby:
    * Switch back to location list
    * Don't check for b:undo_ftplugin existence, assume it
* Save and restore compiler instead of internal options
* Add bash, ksh, sh, and shellcheck compilers
* Rename mail/format_flowed.vim to mail/flowed.vim
* Rename sh/bash_han.vim to sh/han.vim
