Automatically copy TM to given location

Main idea: Create an option to automatically copy the project TM to a directory which has been set by the user.
Possible implementation: In the Project Properties dialog, add a file location field for a "TM repository," ie. a place where the project TM will be copied automatically. This could be made to occur, perhaps, whenever the translation documents get created.
