Fix for the Generic.test_nested_scripting() system test.

A data pipe is needed.

Added a system test for nested scripting.

Fix for the execution locking when an auto-analysis is launched from a script.

The lock is not released and a new one acquired. Instead the mechanism is script, just as it is
for nested scripting.

Bug fix - the script path is now being removed from sys.path.

This was causing incorrect scripts to be loaded if exec_script() is run multiple times.

Modification of the execution lock debugging print outs.

More informative nesting information in the execution lock debugging.

Fix for running scripts - the '.' character is now disallowed as module import cannot work.

Renamed all the frame order scripts so that they have valid module names and can be imported.

Removed all execfile() calls by switching to the script() user function.

This is for security and for handling the execution locking mechanism properly.

Deletion of the peak_list_handling branch - it is now merged back into the main 1.3 line.
