Add project: Lowercasing filenames causes problems

When uploading the map with submaps, the contents of the zip file are lowercased. This causes errors, if the root file, referenced in the mapping file, has uppercases in it. Attached an example: acsn_demo.zip fails to upload (ACSN_main.xml root file not recognized), while acsn_demo_wl.zip passes the parsing step (root file now is acsn_main.xml, mapping file is corrected).
