database tweak for path name for remote - default too short

[dcbour]

The table monitors, field path has a default length of 64. This I found too short to get an authentication string in if using remote monitors. I found that it kept getting truncated and drove me crazy to find out why it wouldn't authenticate until I realized the data wasn't even being passed correctly. Changing this to 255 solved the remote access issue I had.
