[Linux] Cabinet is forcing lowercase on Linux, causing files to not be found.

[tabularelf]

Since Linux is case sensitive (unline Windows and MacOSX), so it is imperative that file names match exactly.
The issue however is that Cabinet is forcing lowercase anyway. Which causes issues on Linux, as files cannot be found.

This can be remedied by changing this in line 126 of Cabinet static _force_lowercase = !_is_microsoft && os_type != os_macosx; to static _force_lowercase = false;.
