Double backslash required for paths in config.properties

[bng919]

All paths in config.properties require double backslash \\ in paths to be parsed correctly as a single backslash followed by certain characters (eg, \n, \r, etc) are interpreted as single characters. This is time consuming for the user as they must add the second backslash manually.

Modify ConfigurationUtils to read the strings correctly if only a single backslash is provided.
