Trying to copy the script file into the data folder when a data object is created (not working yet)
Bug workaround: qtlab was complaining about visa.set_visa because the visa module was not loaded from the qtlab folder but from the python installation
add update function to scripts class to reload scripts (does not yet find new scripts)
fix update function
Add argument "copyScript" to data object:
you can pass the key of a script file (i.e. filename without ".py", e.g. "d = qt.Data(name='dataFileName', copyScript='scriptfile')  )
when the data file is created, this python script will be copied into the data folder
ignore .project files
