Switch to using struct FS_Limits inside Dialog_Partition_Resize_Move (#787204) 

Changes the internal code in Dialog_Partition_Resize_Move to use
fs_limits instead of fs.MIN and fs.MAX.  The limits are still passed
into the constructor via struct FS and it's members .MIN and .MAX but
immediately used to assign to fs_limits.

Bug 787204 - Minimum and maximum size of the UDF partition/disk
