improved LoadDLL

+ improved GetArgNumberFromFunction: now it can guess how many
parameters a cdecl has
+ added new column in the exported listview: now it will guess the
function type (cdecl, stdcall, etc)
+ fixed LDE64.h: oh my... on 32bit LDE was using DWORD64 as return value
instead of DWORD
+ GUI: added chkPause button
