Update devel/fossil to 2.17

Changes for version 2.17
------------------------

  *  Major improvements to the "diff" subsystem, including:
     * Added new formatting options: --by, -b, --webpage, --json, --tcl.
     * Partial-line matching for unified diffs
     * Better partial-line matching for side-by-side diffs
     * Buttons on web-based diffs to show more context
     * Performance improvements
  *  The --branchcolor option on fossil commit and fossil amend can now take
     the value "auto" to force Fossil to use its built-in automatic color
     choosing algorithm.
  *  Fossil now autosyncs prior to running fossil open.
  *  Add the ticket-default-report setting, which if set to the title of a
     ticket report causes that ticket report to be displayed below the search
     box in the /ticket page.
  *  The "nc" query parameter to the /timeline page causes all graph \ 
coloring
     to be omitted.
  *  Improvements and bug fixes to the new "fossil ui REMOTE" feature \ 
so that
     it works better on a wider variety of platforms.
  *  In /wikiedit, show the list of attachments for the current page and list
     URLs suitable for pasting them into the page.
  *  Add the --no-http-compression option to fossil sync and similar.
  *  Print total payload bytes on a fossil sync when using the --verbose option.
  *  Add the close, reopen, hide, and unhide subcommands to the branch command.
  *  The "-p" option to fossil branch list shows only private branches.
  *  The Markdown formatter now interprets the content of block HTML markup
     (such as <table>) in most cases.  Only content of <pre> and \ 
<script> is
     passed through verbatim.
  *  The wiki list command no longer lists "deleted" pages by default. \ 
Use the
     new --all option to include deleted pages in the output.
  *  The fossil all git status command only shows reports for the subset of
     repositories that have a configured Git export.
  *  The /chat configuration was reimplemented and provides new options,
     including the ability for a repository administrator to extend the
     selection of notification sounds using unversioned files.
  *  Chat now uses fossil's full complement of markdown features, instead of
     the prior small subset of markup it previously supported.  This
     retroactively applies to all chat messages, as they are markdown-processed
     when they are sent instead of when they are saved.
  *  Added a chat message preview mode so messages can be previewed before
     being sent. Similarly, added a per-message ability to view the raw
     un-parsed message text.
  *  The hotkey to activate preview mode in /wikiedit, /fileedit, and
     /pikchrshow was changed from ctrl-enter to shift-enter in order to align
     with /chat's new preview feature and related future changes.
