Store settings as .ini - Githubissues

Currently the users API key is stored as a Qsettings variable

This is no longer seen as best practice

When others are debugging code we do not want them finding themselves here and modifying other settings sorted here

config_path = os.path.join( QgsApplication.qgisSettingsDirPath(), "lds-plugin", "config.ini" )

QgsApplication.qgisSettingsDirPath() being the .qgis2 folder
