Buildsystem: Make core buildable under Windows again

- changed OpenSSL detection of headers around slightly
- changed paths to MySQL-headers on Windows in a few files
- removed precompiled header for scripts being built when building game
- added requirement of building revision.h to be built before building shared
- added some generic buildfixes (thanks zor)
- use resource-files, allowing for icons to show up on windows
