Subject: [PATCH] HAS_REMOTE_API support for Windows. Adds support for MingW
 too. * HAS_REMOTE_API still defaults to 0 * When HAS_REMOTE_API=0 only
 libraries advapi32.lib, ole32.lib and shell32.lib are required. * Setting
 HAS_REMOTE_API=1 requires curl: https://curl.haxx.se/libcurl/ *- Also need to
 manually install 7-Zip (http://www.7-zip.org). *- Will automatically install
 Tinyxml2 (http://www.grinninglizard.com/tinyxml2/). *- Will automatically
 install
