declare all global inter-dependant objects in main.cpp and get rid of init_priority attribute

 * we cannot use weak symbols in MinGW, so we avoid init_priority for symbol
   initialization by compiling the empty definitions into
   sciteco-minimal but the real ones into sciteco
   (had to add new file symbols-minimal.cpp)
 * this fixes compilation/linking on LLVM Clang AND Dragonegg
   since their init_priority attribute is broken!
   this will likely be fixed in the near future but broken versions
   will be around for some time
