Re #6563. Don't get stuck waiting for license acceptance.

The dmg has the GPL license embedded within it, which the
user is required to accept before the volume is mounted.
This accepts it by piping acceptance into the command. The
output to /dev/null deals with the fact that the license is
multi-page (effectively it scrolls to the bottom which is where
the 'Y' needs to be entered).
Re #6563. A way of installing that doesn't hang!

I'd only tested the previous method I tried on the command
line. Turned out that didn't work within python.
Fix a few createAlgorithm references.

Re #8882. Enable script to be run if called from another directory.
Re #8882. Use the NSIS installer by default and always.

The MSI installer is long-dead so we don't need to leave the option
hanging around (especially as the default). The -v option is still left
in the list of possible flags for backwards compatibility, but it does
nothing.
Re #8882. Generalise the path to the stresstesting module.

So that this script can be run from a different working directory.
Re #8882. Forgot the import.
