* #undef Bool with Qt4 as well as with Qt5.
* #undef min, #undef max from <X11/Xlibint.h>.
* #include <fixx11h.h> just after hotkeywrapper.hh. Unfortunately this
header can not be included in hotkeywrapper.hh directly because
some of the undef-ed words are actually used in hotkeywrapper.cc.
* #include <fixx11h.h> after <X11/Xlib.h> in mainwindow.cc just in case
hotkeywrapper.hh stops including this Xlib.h header in the future.
These changes should make future compilation errors less likely.
For example, without "#undef min" in hotkeywrapper.hh, including
<iomanip> in mainwindow.cc after the mainwindow.hh include resulted in
the following GCC 8 compilation error:
/usr/include/c++/8.2.1/bits/locale_facets_nonio.tcc:945:22:
error: expected unqualified-id before ‘(’ token

Before this change ScanPopup::applyWordsZoomLevel() was called before
the primary connection to ScanPopup::currentGroupChanged() in
ScanPopup's constructor. This meant that disconnect() had no effect and
connect() established the first connection during the first call to
ScanPopup::applyWordsZoomLevel(). This caused 2 issues:
1. Since the connection happened before the filling of ui.groupList
in ScanPopup's constructor, the current group in scan popup was always
"All" on Goldendict start.
2. Since the connection was not unique, the slot was connected twice
to the same signal, and it was actually called twice.
The bug was introduced in 92e8c85eec.
Executable icon could be a security risk. Closes #823.
This commit eliminates one of the 2 non-critical "make install" errors
described in #1001. Fixing the other error requires removing executable
bit from goldendict.desktop, which may cause issues to some users.
Examples of code that could access the destroyed log file object:
* a destructor of a local object declared before logFile in main();
* a destructor of a global object;
* termHandler() invoked after logFile was destroyed either normally
or because of an uncaught exception.
The article view focus is necessary to navigate a word definition via
keyboard rather than mouse. The shortcut - Ctrl+N - is the same as
the one in the main window for the corresponding action.
* Run the freedesktop.org-specific code only on X11 (not on Mac).
* Use a (hopefully) unique destination .desktop file name to prevent
clashes with a goldendict.desktop file possibly created and customized
manually or by a system preferences tool.
* Allow different executable and .desktop file names because there is
no real dependency between them.
* Improve performance slightly with an early return.
Destroying and creating a scan popup instance twice in
MainWindow::editPreferences() is wasteful.
2b9dd55804 added the unconditional second
makeScanPopup() call below but didn't remove the existing call,
probably by mistake.
