Bug fixes

• Do not erase sparse, compressed or encrypted files when FL2KB erasure is selected to prevent disk corruption.
• Fix Win32 Eraser builds to be truly Unicode builds.
• A few 64-bit fixes.
• Ensure that Eraser uses the latest runtimes packaged with the installer. This should fix hangs when using the Context menu.
• Fixed the About dialog after migrating to Unicode
• Sign all binaries packaged with the installer
• Allow erasing UNC paths
• Fixed memory exhaustion when doing a free space erase for FAT drives
• Migrate non-Unicode custom erasure methods to the Unicode methods so that old custom erasure methods are preserved upon upgrade
