Summary of changes

• Allow to switch default completion engine via environment variable
  or GSetting.
  
• Add unix pipe like completer that allows to get completions
  from the output of an executable.
  
• Add hunspell based completer for typo correction
  
• Word completion itself isn't considered experimental anymore. The
  completion engines using surrounding text like the presage based completers
  still are.
  
• Some style fixups

Detailed changes

phosh-osk-stub (0.27.0) experimental; urgency=medium
.
  * Update doap file.
    Fix some copy and paste errors when bringing that one in from
    phosh.
  * Add appstream metainfo
  * tools: Properly pick up default phoc.ini
  * tools: Use headless backend for screenshots.
    No need to bring up a window on the host and this way it's
    simpler in CI.
  * build: Detect available completers.
    The check for fzf is actually a runtime check but use it as this is
    solely for testing we assume built-time env == runtime env.
    We don't break any existing configurations since switching completers
    needed code changes anyway.
  * Add completer-manager.
    This class is responsible for mapping completion engines to keyboard
    layouts / locales.
    It keeps the input-surface clear from any knowledge about which
    completers are available.
    This introduces the minimal object which just returns the presage
    completer. The next commits will then add more completers.
  * input-surface: Hook up completer-manager.
    This already allows to switch the default completer via an environment
    variable.
  * completers/fzf: Drop commented out code
  * completers/fzf: Take an error location and use initable.
    This makes completers consistent. We use that as an opportunity to check
    if the word list is present.
  * completer-manager: Allow to select completer via POS_TEST_COMPLETER.
    This moves the default completer from compile time to program startup
    time.
  * Use a common dependency for all completers.
    This way we can keep the knowledge about available completers in
    completers/ (and PosCompleterManager).
  * shortcutsbar: Make css actually apply
  * css: Add section markers
  * doc: Fix POS_TEST_COMPLETER docs.
    The value descriptions ended up in the wrong place.
  * completers: Add unix pipe like completer.
    The completer gets the current preedit on stdin and can output a list of
    completions. We default to `cat` which just offers the current preedit
    as completion.
  * input-surface: Don't leak completions pos_completer_get_completions is
    "transfer: full"
  * completion-bar: Use a bold font for suggestions.  Makes them a bit more
    prominent
  * pipe: Only force kill command if still running
  * build: Move presage definitions to completers
  * completers: Make name a r/o property and set it
  * completer-manager: Allow to set default completer via GSetting.  Keep
    presage as the default.
  * osk-widget: Set language and region.  This corresponds the parts of a unix
    locale like <lang>_<region> although we use all lowercase.
  * completer: Split language and region.  This avoids leaking implementation
    details of the layouts into the completer.
  * input-surface: No need to switch language when switching to terminal
  * ci: Switch to image with libhunspell-dev
  * packaging: Enable hunspell completer.
    It's easier to set up than presage and pretty useful in en-us at least.
  * completers: Add simple hunspell completer.
  * Allow to use either hunspell or presage.
    We prefer hunspell atm. Later on we want presage and hunspell active
    at the same time.
  * doc: Update manpage.
    Document gsettings, mark completion in general as no longer
    experimental.
