added nightly builds for Windows 32-bit PDCurses

* These builds generally work, but function keys appear to be broken.
  This does not happen when building with the latest PDCursesMod on my machine.
* <EC> appears to be broken.
* We try to link everything statically since MSYS provides actually working
  static libglib builds.
  Unfortunately, their gspawn helper executables are still linked normally,
  so we have to pull in most DLLs anyway.
  Considering that GTK cannot be linked statically, we should perhaps
  simply link the Curses builds dynamically as well.
