Removable files

One issue with PyInstaller, it seems, is that unnecessary files are included. The creator of Anki told me (@olivierkes) that one of the difficulties was to find what libraries to remove.

While trying to find the cause of the annoying accentuated characters bug in Linux (see for example issue #207), I realized that manuskript could still be run even if all the following files are removed:

(tested on Ubuntu 16.04.3 LTS xenial with manuskript-0.5.0-linux64.zip).

• Haven't checked all the functionalities, but most of manuskript works.
• Notable exception: QtWebEngine / QtWebKit is disabled. Even when adding all the PyQt* and libQt5*.
• Removing all of that, the accentuated characters bug is still present.

In other terms, only those are necessary:

base_library.zip
libpython3.4m.so.1.0
libQt5Core.so.5
libQt5DBus.so.5
libQt5Gui.so.5
libQt5Svg.so.5
libQt5Widgets.so.5
lxml.etree.so
manuskript
PyQt5.QtCore.so
PyQt5.QtGui.so
PyQt5.Qt.so
PyQt5.QtWidgets.so
sip.so    

In qt5_plugins

Can be removed:

t5_plugins/platforms/libqoffscreen.so
qt5_plugins/platforms/libqlinuxfb.so
qt5_plugins/platforms/libqminimal.so
qt5_plugins/platforms/libqkms.so
qt5_plugins/platforms/libqminimalegl.so
qt5_plugins/platforms/libqeglfs.so
qt5_plugins/accessible/*
qt5_plugins/imageformats/*
qt5_plugins/bearer/*
qt5_plugins/printsupport/*
qt5_plugins/platformthemes/*

• All those files are not necessary to manuskript
• Accentuated bug still present

In base_library.zip

• encodings: We can remove most of the encodings in encodings, leaving __init__, aliases, latin_1, utf_8. Bug still present.

• Others: None of the others files can be removed, except collections/abc.pyc and maybe collections.__main__.pyc as well as _bootlocale.pyc.
