use FileSize type for humanReadableSize() parameter
Review Request #102870 - Created Oct. 15, 2011 and submitted - Latest diff uploaded
Filelight internally uses a FileSize type in fileTree.h to represent file sizes. However, File::humanReadableSize() takes the size as uint instead of FileSize, causing overflow issues if FileSize is defined as larger than uint.
Built filelight in kdeutils-4.6.5 and git master with this change and it caused no issues.
