* ODS.cs:

* 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.
