The kvasd binary need only be downloaded if the MD5 hash for it has
changed.
Also fixed a defect in the status check of the MD5 hash download.
Also switched to HTTP protocol as it is quick and gives clearer error
messages.

To comply with the WSJT_X GPL v3 license, the closed source KVASD
executable must be delivered separately and optionally to end
users. To facilitate this a new install option has been added to the
Windows installer to install KVASD by downloading it at install
time. The installer first downloads the KVASD EULA from the Internet
and presents it to the user for reading and agreement. If agreement
is given the KVASD binary is downloaded from the Internet and
checksummed using an MD5 hash, if that passes, it is installed along
with WSJT-X. An uninstall record is also written to ensure that, if
installed, KVASD will be un-installed if WSJT-X is un-installed.
To facilitate this enhancment to the NSIS installer the standard CPack
NSIS installer script template has been overridden with a project
specific version. This version also implements the more modern and
recomended nsDialogs mechanism for installer custom page construction
including the install options page. See CMake/Modules/NSIS.template.in
for details and CMakeCPackOptions.cmake.in for usage in this
installer.
Merged from branch wsjtx-1.4.

User manual and kvasd downloads are occasionally timing out with a 10s
timeout.
