1.4 Reuse fieldmaps, csv import action + various bugfixes.

Features

• Added csv action, which doesn't fieldmap but only imports the csv. This is added for debugging purposes and therefor isn't documented.
• Implemented use="" attribute for the <fieldmap/> node. See documentation for usage

Fixed

• Updated composer.json
• End of XML file could not be parsed properly. #30
• sourceModel was loaded twice
• Load line 0 when there is no line specified.

The following features were removed:

• Stop logging downloading of images, is useless information.
• [Cleanup] Removed the admin panel notification of the import. This causes more confusion than it solves.
