Implement 'MakeSureDirectoryPathExists'

["P. Christeas" <p_christ@hol.gr>]

Hi, 
I just wrote a little code implementing imagehlp/MakeSureDirectoryPathExists.
I don't have the specs available, so I *assume* this fn does what it says. 

in my code: I try to create the dir and don't fail if it already exists.

Changelog:
	* Implement MakeSureDirectoryPathExists in imagehlp/imagehlp_main.c

Interestingly, my 'diff' revealed 2 more  changes I have in my local 
repository. Please tell me if they should be applied.
