Add command line flag for toggling precut For devices that support cutting before the current label ("precut"), change the default to no precut and add a command line flag to turn it on.

Browse Source 
Odd behavior in testing with my PT-H500: When printing with precut, and then printing the next label without precut, the next label still gets a precut. i.e. the label with the precut flag gets cut on both ends, even if the next label does not have this flag. The label after that works as expected.

I'm unsure if this is printer behavior or if it could be resolved by sending additional commands somehow (maybe resetting the flag).
