Run() - doc precision

[Zedna]

From AutoIt changelog:

3.2.2.0 (23rd December, 2006) (Release)
- Changed: @error set to WinAPI GetLastError() for Run().

But there is no information about this in Run(), RunWait() helpfile section.

There is only:

Return Value

Success: The PID of the process that was launched. 
Failure: Returns 0 and sets @error to non-zero.

So better will be:
There is only:

Return Value

Success: The PID of the process that was launched. 
Failure: Returns 0 and sets @error to WinAPI GetLastError().

I'm not sure how useful it is to document this. It wasn't really added to be useful for user's but rather for us in debugging. For now I think it should still be undocumented.
