Update INSTALL.mingw to reflect specific versions; explicitly verbose!

INSTALL.mingw

 Here are some rough notes that might help you create a pidgin-otr Win32 build on
 a Linux system with mingw32. These have been tested on Ubuntu 11.04.
 
-I am listing packages and their build instructions in the order they should be
-built. Good luck!
