Log Message:
Update to 0.54. From the changelog:

Yaml:
 * New module, by Brian Exelbierd (GitHub's #66)
 * Fix the behavior with utf-8 files, thanks to Zero King (GitHub's #112)
 * Add the references from the Yaml file to the po file (GitHub's #117)
   Thanks Zero King.

Texinfo:
 * Fix handling of spaces in menu descriptions (Github's #122 and
   Debian's #758851).

Text:
 * Fix the parsing of fortunes files, which had been broken since
   v0.43. The handling has changed a bit, all msgids are now marked as
   "no-wrap", because the word wrap in fortunes files usually matters.
 * Remove the option for parsing AsciiDoc. There has been a standalone
   module for nearly five years, released with v0.45. The AsciiDoc
   option for the Text module has been deprecated since then.
 * Support pandoc's bibliographic information (title, author, date)
   at the beginning of a markdown file. Also fix a trailing newline
   in some markdown titles (Debian's #894977).

Man:
 * Support .MT and .ME macros for e-mail address markup (Debian's #900965).
 * Support .OP, .SY, and .YS macros for command synopses.

Asciidoc:
 * handle macros with empty target, thanks Martijn Thé (GitHub's #54)
 * Fixed a bug that prevented the asciidoc module to parse correctly four
   characters table marks.

Documentation:
 * Fix many typos and other issues found by Yuri Chornoivan (GitHub's #104)
   and Allan Nordhøy (GitHub's #102) while translating.
 * Remove the last references to the alioth servers and mailing lists.

po4a tool:
 * po4a --keep-translations will not remove your existing translations
   if they fall below the threshold. It won't create badly translated
   files either. Use it if you prefer outdated but translated doc to
   updated but not translated doc.

po4a-build tool:
 * Remove it and all related shell scripts and makefile chunks. It is
   deprecated by the po4a tool since a long time, and I could not find
   any usage of po4a-build either in Debian or using search engines.
