Files downloaded from scriptrepo should be immediately usable in scripts

[Nick Draper]

We should automatically add the python directories for the script repository such that any library downloaded can immediately be used in a script in Mantidplot.

Tester:

• Open ScriptRepository
• Download file: direct inelastic->SNS->MaskBTP.py
• Download file: direct inelastic->SNS->reduce_from_autoreduce_script.py
• Double-click file: reduce_from_autoreduce_script.py
• It will open the ScriptWindow
• Execute all
• At ISIS: it will execute till line 229, and them call exit. But, it was alive and it passed the line: 11, from MaskBTP import ... which means that this folder is inside the python path.
• Close MantidPlot.
• Restart MantidPlot
• try to execute the reduce_from_autoreduce_script again, and receive the same output.

Add directories to the python.directories

This change makes the scripts available for the next time Mantid plot starts.

Make script usable for the current session of Mantid

In order to make the script usable as soon as it is downloade, it is not enough to update the pythonscripts.directories as the last commit did, but you have also to add to the python sys path at the current running session.

Running python code is not possible inside the Framework/ScriptRepository level. So, a notification strategy was used in order to trigger a method of MantidUI, which can execute the python code that is necessary to add the new paths to the python sys.

Adjust the paths for windows backslashs

Adjust the strings to parse all the backslashes and make them normal slashes. Windows accept both kind, so, there is no problem of having them inside the pythondirectories.

I decided to use the default folder for the script repository, but the forgot what this was. It would be useful for this information (whatever folder the user chooses) to be displayed.

[Karl Palmen]

MaskBTP.py found with aid of File explorer search. When I ran it, it ran quickly without any error messages or workspaces created ending on line 42.

[Karl Palmen]

When I ran reduce_from_autoreduce_script.py, it exited with an attribute error on line 227. It appears to need arguments.

[Karl Palmen]

Clicking on the file in the script repository window successfully opened script window with file in it after the script window was closed. However there was bad behaviour when one opens a 2nd or 3rd file by this method, which will be reported as a separate ticket.

Gesner confirmed it was OK for the reduce... script to work to line 227 (rather than 229).

[Karl Palmen]

The reduce... script works in the same way in a second run of Mantid.
