Deplored

Zip archives created under Windows may use backslash as internal path separator. This patch works this around by replacing any backslash with regular slash. Concerns: https://github.com/icsharpcode/SharpZipLib/issues/617

These changes cover: - uploading mod archives created in memory (MemoryStream) - uploading encoded images (byte arrays) - EncodedImage class - for passing target image extension
