* HPFS.cs: * ISO9660.cs: * AppleMFS.cs: * AppleHFS.cs: * AppleHFSPlus.cs: Moved datetime conversion to DateHandlers class. * Symbian.cs: Identifies .SIS files. Yes I know it's not a filesystem but I needed it so. * Main.cs: Corrected typo * FileSystemIDandChk.csproj: Added datetime conversion handling class, Symbian .SIS installers, ext filesystem and ext2/3/4 filesystems. * ext2FS.cs: Detects ext2, ext3 and ext4 filesystems up to Linux 3.1 kernel. * extFS.cs: Detects ext filesystems. Untested as no Linux 2.0 was available at time :p * DateHandlers.cs: Moved all datetime convertions from plugins to central class. git-svn-id: svn://claunia.com/FileSystemIDandChk@11 17725271-3d32-4980-a8cb-9ff532f270ba
