PluginFix v1.01[By BoB / Team PEiD]

===================================================================
// This simple tool converts OllyDbg and ImmuntiyDebugger plugins to be used with the new ImmDbg v1.80
// It needs to change the Imports and Exports of a plugin to do this, so it will NOT work on packed plugins!
===================================================================

//[ v1.01 ]
//
// Changes:
// o Fixed problem that if any section raw pointer was 0 then no dos/pe header written
// o Added support for OllyDbg Plugins
