​from processing.script.ScriptUtils import *
print ScriptUtils.scriptsFolder()

if run in stand-alone, returns a wrong folder:
​/home/agraser/temp/standaloneprocessing/processing/scripts
(/home/agraser/temp/standaloneprocessing is the location of my stand-alone
script)

​instead of the correct folder in the QGIS console:
u'/home/agraser/.qgis2/processing/scripts'.

Seems like we are getting closer to where the real issue is hiding. Imho it
makes little sense that the paths appear relative to the stand-alone
script's location.

Best wishes,
Anita
