Update to tig-0.12.1.

Changes:

tig-0.12.1
----------
   Improvements:

 * Status view: revert uncommitted diff chunks and unstaged files with
   changes. Bound to ! by default.
 * Main view: use --topo-order also when rev-list arguments are given on
   the command line.
 * Log view: support for refreshing.

   Bug fixes:

 * Status view: use ls-files' --exclude-standard so user specific ignore
   rules are effective. The option was added in git version 1.5.4.
 * Stage view: fix assertion failure triggered when updating while status
   view is not displayed.
 * Help view: avoid confusion by showing "(no key)" instead of "?" for
   unbound requests.
 * Reload repository references when refreshing the main (and log) view.
 * Do not maximize views when refreshing.

tig-0.12
--------
   Improvements:

 * F5 also refreshes the current view.
 * Allow line graphics to be disabled with new line-graphics option.
 * Main view: also include the reference names when searching.
 * Main view: support for refreshing.
 * Main view: disable boundary commits by default. Use --boundary when
   they should be shown. (Debian bug 498628)
 * Stage view: add stage-next action to jump to next diff chunk that can
   be staged. By default bound to @.
 * Configure: check for the ncurses header files.
 * Add author-width option to costumize the width of the author column.
   For example, put the following in ~/.tigrc: set author-width = 10

   Bug fixes:

 * Fix regression when staging all diff chunks in a section.
 * Bind the maximize view action to O; it conflicted with the keybinding
   to launch the merge tool in the status view.
 * Fix problem with $(cmd) usage in shell code. Some shells (jsh)
   installed as /bin/sh does not support it.
 * Do not show incomplete boundary commits when --no-walk is used.
 * Documentation: Rename gitlink macro to support AsciiDoc 8.2.3.
 * Ignore pipe reads with errno "Success" reported after a signals, for
   example when refreshing doing background loading.
tig-0.11
--------
   Incompatibilities:

 * Remove parsing of deprecated options: -g, -l, -d.
 * The first seen -- will stop option parsing and is passed to git
   instead of breaking out of tig's option parsing.

   New features:

 * Blame view; bound to B by default, reachable from the command line and
   the tree, status, and stage views.
 * Blame/main view: allow display of date, author, and references to be
   toggled on/off. Bound to D, A, and F respectively.
 * Add action to maximize the current view.
   Improvements:
 * Show the current branch in the status view.
 * Show local/light-weight tags.

   Bug fixes:

 * Fix regressions for the pager mode.
 * Fix refreshing of the index with working directory info.
