[svn] Further attempts to make troggle work on windows using surveys stored on an external server

settings.PHOTOS changed to setting.PHOTO_ROOT
Made databaseReset.py get info from external server if appropriate (hope this did not break linus disk based scripts)
Still needs more work, to get everything working
Auto create photos directory if it does not already exist
