#45 Minor ImageLib fixes

[Eloi George]

Function create_library() wasn't fully explaining why
it exits when the directory creation failed due to
improper permissions, so I changed the code to use the
core function PHPWS_File::makeDir() and added the
following exit message:

'ERROR (PHPWS_IMGLib): Couldn\'t create directory
"'.$a.'"<br />Make sure that the proper permissions are
set in the parent directories.'

ImageLib also generated the following Notice:

Notice: Undefined variable: bg in
/www/r/realvidreams/htdocs/933/core/ImgLibrary.php on
line 395

This was fixed by inserting the following after line 393:

$bg = '';

Sorry. Just wanted to keep the reporting trail intact.
The fix for create_library() stems from a bug report filed
for phpwsbb at
