Log Message:
fvwm3: Update to 1.0.2

based on a private patch from snow flurry, thx!

There have been a tonne of bug-fixes, and what's listed below are some
key-highlights. Please do read the full CHANGELOG in detail for more
information.

Breaking changes:
* Deprecate librplay support in FvwmEvent
  * This therefore means librplay as a dependency is no longer required.
* documentation: remove docbook in favour of asciidoc (ThomasAdam)
  * This therefore means that xsltproc as a dependency is no longer
    required, but asciidoctor will be for compiling man pages.
* documentation: --enable-htmldoc has been removed -- generating HTML
  documentation is longer possible.

Implemented enhancements:

* New Status command in JSON format (over a FIFO) for use with external
  bars such as lemonbar
  * Add expansion variables for a window's X/Y page
  * Introduced a compat-wrapper for FvwmCommand written in Python3
