Kurt Pfeifle 315c3e7dbc Enhancements to AppImage
Enhance 'build-appimage' script:

- add initial comment block and comments for all major steps in the
  script for the benefit of casual users of the script
- 'configure' to build HTML + PDF documentation
- do not remove the man pages from the AppDir (will be used by custom
  AppRun script)
- use a bigger icon
- use '-g' for appimagetool so it can figure out the 'updateinfo' string
  on Travis CI
- output big fat warning to users who build AppImage in non-"Trusty"
  environments

Add 'AppStream' metadata file

This serves to satisfy desktop environments who want to automatically
create menu entries, show screenshots and display software descriptions.

Note, this file (qpdf.appdata.xml) may need more tweaking since the
Freedesktop folks aren't exactly sure themselves how their 'standard'
should exactly look like, and they changed their validation tools
quite a bit over the recent years in incompatible ways...

Extended and enhanced customized AppRun script

- Add a '--ai-usage' invokation param to the AppImage which serves as
  a starting point to explore the other embedded options
- Support displaying of manual pages by running AppImage with added
  parameter '--man ...'
- Also include HTML/PDF documentation, READMEs and licenses into AppImage
- Support for more parameters: '--list-man', '--list-pdf', '--list-readme',
  '--list-license', '--list-html', '--list-exe', '--pdf', '--readme',
  '--license', '--html' and '--show-apprun'
- Support 'fix-pdf' and 'zlib-' as sub-commands (not just as symlinks)

#
# This script is mainly meant to build an 'AppImage' from GitHub sources of QPDF via Travis CI on an
# Ubuntu Trusty (14.04) LTS system (see https://appimage.org/).
#
# But it also allows Linux users to build such an AppImage on their own systems. Please read
# 'README.md' from the top level Git sources to see what preconditions you must meet to build QPDF
# in general. The same apply to build an AppImage. Then follow these three steps:
#
# 1. Clone Git sources: `git clone https://github.com/qpdf/qpdf.git git.qpdf`
# 2. Change into git dir: `cd git.qpdf`
# 3. Run this script: `bash appimage/build-appimage`
#
# The resulting AppImage will be placed in './appimage/build/QPDF-x86_64.AppImage'.
# Read the output of the script for hints in case something goes wrong.
#
# You may pass custom options for the configure step by setting them into the 'CUSTOM_CONFIGURE'
# environment variable and exporting it before running this script. For example:
#
# export CUSTOM_CONFIGURE=" --enable-test-compare-images [--more-other-options]"
#
# ATTENTION:
#
# 1. To build the AppImage you should have a working internet connection.
# Reason: the script downloads the most recent 'linuxdeployqt' utility for building the AppImage.
# 2. If you build the AppImage on a too recent Linux distribution, it may only work on the exact
# distribution you build it on. For an AppImage to work on a wide range of different
# distributions from the last 3-4 years if should be built on Ubuntu Trusty (14.04).
