[Edserplo_users] Update

[Steve Loch]

This update should resolve the problem of scatter plots (Polly), settings files (Stephanie), and also provides line style 6 (Polly). Both scatter plots are accessible though to use the CMD one the channel names must be exactly 'East' and 'North'.

Rashid is working on thickening the lines in the context of hardcopy generation (.png files) (as per Serplo)  and has made the inversion of background optional. This may be available tomorrow.
