Changes:
1.1
---
 * The formatting program sfeed_curses is now merged in the sfeed repo.
   This is a program for viewing items in a curses UI.
   sfeed can still be built without it if its considered bloat with:
         make SFEED_CURSES="".
 * sfeed_mbox: escape the link and enclosure text when using HTML content
   with the option SFEED_MBOX_CONTENT="1"
 * sfeed_mbox: add link as base URL for HTML content.
 * sfeed_mbox: use 64-bit for the checksum number on 32-bit systems.
 * sfeed_content: optimizations to the awk script for the UTF-8 locale and
   string replacements.
 * sfeed_content: add link as base URL for HTML content.
 * Documentation improvements and more examples in the man page.
 * Small code-style improvements.
