Source function FIND_PROC_BY_NAME based
   upon the Ravi Kochhar (kochhar@physiology.wisc.edu) code
Thanks iceman_k (FindProcDLL plugin) and
   DITMan (KillProcDLL plugin) for direct me
NSIS UNICODE compatible version (1.6) by brainsucker
   (sorry, installer missing, i'm too lazy :)

Features:
- Find a process by name
- Kill all processes with specified name (not only one)
- Close all processes with specified name (first tries to close all process windows,
waits for 3 seconds for process to exit, terminates if still alive)
- The process name is case-insensitive
- Win95/98/ME/NT/2000/XP/Win7 support
- Small plugin size (4 Kb)
- NSIS UNICODE support (just rename nsProcessW.dll into nsProcess.dll)

**** Comment from brainsucker ****
I'm actually not using macros in my code, plugin calls are easy:

nsProcess:_CloseProcess "notepad.exe"
Pop $R0

**** Unload plugin ****
${nsProcess::Unload}
