Windows build script will now save, and check, the last build commit and
skip building if there are no new commits since the last automatic build.
See #1917.
This is so the new JSON library we're using doesn't break things. :)
Note also the "8.1" added to the end of the vcvars line in the batch
file, so the correct SDK is selected.
Without it, when both MSVC 2015 & MSVC 2017 are installed, the MSVC
2015 installation (by default) will be unable to find rc.exe.
NSIS was used up to v3.10.1 and then we moved to MSI. The Windows Installer will now be able to detect if a previous version was installed using NSIS and uninstall it before installing the new version.
See issue #1642.
All the new committed files are the same as the current files, but have "_new" suffix so they can be tested without breaking the current build system. Once tested, the old files can be removed and the new ones renamed.
See issue #1630.
The *.qm translations files were missing from being bundled with the installer, so the default strings weren't translated and were defaulting to English.
See #1592.
Commit 7394640 added a workaround for a bug in QNetworkAccessManager about a year ago but the required DLL "qgenericbearer.dll" for it wasn't included with the build which was causing "The network is not accessible" error.
The required file is now included till the bug is fixed and probably
should be removed when it is no longer needed.
See https://bugreports.qt.io/browse/QTBUG-40332
See also #1592.
Since Qt 5.10, the Windows Vista style has been moved to its own plugin. This plugin must be included in order to show the new style. It will be included for the 64-bit build only for now, since we are using a different Qt version (5.7) for the 32-bit build.
See #1580.
Sometimes the installation log is required to debug failed installs. This commit will make sure the MSI will automatically create a logging file every time it is used to install, repair, or remove the application.
See #1545.
