[z2259] Further fixes for extract tools close #8 Thanks danielsreichenbach

The patch will allow map files to be extracted with binaries built on Linux, since they currently do fail when extraction maps, since Linux is case-sensitive when it comes to file names.

This removes the need to run pre-built Windows binaries under Linux to extract and assemble map data.
