[Fixed] Updating checksum by import-and-export fail

[dullneko]

Updating checksum by importing and exporting custom filter fails at ABP 204b 3445.

To reproduce,
1. Add a local subscription.(*)
2. Import the text file as custom filter.
3. Then export the custom filter as custom filter and overwrite the text file.
4. Try to update the local subscription manually.
5. You'll see checksum mismatch.

*)You may download Easylist to your desktop and add it as a local subscription.

I use Windows 7 HP, Japanese version
Firefox 12 stable and 13 beta
