Enqueue .SFV's During File Checking

[Big-O Mark]

In the next version of hkSFV32, you will be able to choose single or multiple instance mode.

In single instance mode, if you perform any action that requires file checking (drag & drop, shell extension, double-click an .SFV, etc.) while you are currently checking a file, hkSFV32 will automatically enqueue the action.

In multiple instance mode, if you perform any action that requires file checking, hkSFV32 will open a new window and perform the action immediately, and simultaneously with the other action you are performing.

Pretty handy, and fun to play with :).
