Not able to open another file in new tab of existing Snaketail window through command line.

Steps will reproduce the problem?

1. Open Command Prompt
2. Run the following commands:

3. echo "foo" > c:\foo.log
   C:\Progra~1\SnakeTail\SnakeTail.exe "C:\foo.log"
   echo "test" > c:\test.log
   C:\Progra~1\SnakeTail\SnakeTail.exe "C:\test.log"

4. observe new file opened in separate window.

Expected behaviour:
I expect SnakeTail would attempt to open new files in new tab of existing SnakeTail window if there is.

This issue might be similar to : #87, but it should work from command line as well.
